Top 7 Web Development Languages
Web development is arguably one of the most critical responsibilities in the tech field, as well as one of the most visible and promising. So it's probably no surprise to anyone, even those outside the tech space, that web developers, especially those with extensive experience, skills, knowledge, and a strong portfolio, are in high demand.
Let's start from the beginning: Web development has been around since the 1990s, when the Internet was just beginning its humble existence, and it's safe to say it will never disappear. Over the decades since those early years, it has become an integral part of our daily lives, as we all know well.
However, the sites that appeared in the early years are nothing more than an interesting footnote in history. If you look at an old website, if you can even find one, you'll likely laugh at how simple and outdated it seems.
Of course, it's safe to say that the field and practice of web development have come a very long way since then, as we all know. Modern web design has evolved into something much more complex, useful, and engaging for audiences worldwide. It's what we've all come to expect: dynamic, engaging, attractive, compelling, and communicative tools.
Gone are the days of static websites with flat text. They have been replaced by dynamic, interactive sites that can do just about anything—from automatic updates, animated menus and elements to e-commerce. Everyone uses the Internet, and everyone expects to find their favorite tools, businesses, and events there.
And with the right web development skills, there's almost nothing that your in-house developers or developers you hire from a web development outsourcing company cannot create.
No matter where you find web developers, it's important that they have the necessary skills to get the job done. This means they are proficient in the programming languages required to design and build websites that best suit the task at hand. Today, the Internet is overflowing with interesting websites and web applications, and to stand out in a crowded space, you need to be able to choose the best of the best.
But what programming languages do your developers need to know to create modern, dynamic, functional, and attractive websites and web products that will truly make you and your business shine and attract more visitors and consumers?
Let's look at the top 7 programming languages for building attractive and useful websites, web pages, and web applications, as well as some tools you need to know to fully leverage these programming languages.
#1 HTML/CSS
Let's start with the most obvious programming language. Why? Because you won't get far building custom sites without knowing the native programming language. With a combination of HTML and CSS, you can do a lot. However, it's important to understand that to create the dynamic and interesting websites and web pages we are so familiar with today, you'll need the help of other programming languages.
Yes, it's true that these 2 markup languages, as they are also called, are the foundation for creating web pages for sites. But don't confuse HTML and CSS with other programming languages. They are actually completely different languages. These two markup languages, as they are called, are simply the foundation for building websites. And no matter how complex the site is, if you look at the page source, you'll surely see HTML and CSS tags in the code.
| Advantages | Disadvantages |
| Easy to learn and use with a clear syntax | Limited interactivity, requiring additional languages like JavaScript for dynamic content |
| Widely supported with a large and active community | May be limited in functionality and capabilities compared to full-fledged programming languages |
| Essential for creating and defining the structure and layout of web pages | Requires additional languages like JavaScript to provide interactivity and dynamic content |
| Well suited for prototyping and development speed | Can be complex to maintain and update, especially for large or complex websites |
| Integration with other web technologies like JavaScript and PHP to create dynamic and interactive web applications | Can lead to verbose code, especially for complex or interactive sites |
Since HTML/CSS are the fundamental languages for all web design, it's crucial for web developers to be proficient in these two languages. Although you won't be able to go far in building everything your client desires, you'll have the foundation on which to build the rest of the site using a combination of additional web development languages.
#2 PHP
PHP stands for Hypertext Preprocessor and is a scripting language used on the server side (backend) to create simple dynamic websites and web applications. Many of the most popular website frameworks, such as Wikipedia, Etsy, Pfizer, Drupal, WordPress, and even Facebook, use PHP.
PHP is an incredibly popular language for building sites, partly because it is supported by a large number of third-party extensions like .NET, Apache, and MySQL. This support allows PHP to act as a bridge between websites and other services. PHP can also interact with other services such as LDAP, IMAP, SNMP, NNTP, POP3, HTTP, and COM (on Windows).
PHP is also very secure and fast, making it a very useful programming language for enterprise businesses. And because PHP is open and free, it is easily accessible to any aspiring web developer. Of course, experienced developers also use this resource. Additionally, PHP is relatively easy to use, making it a great second step after HTML/CSS. And with plenty of straightforward documentation, your developers can quickly learn PHP.
| Advantages | Disadvantages |
| Easy to learn and use with a clear syntax | Security vulnerabilities such as SQL injection and cross-site scripting (XSS) |
| Widely supported with a large and active community | Performance limitations compared to other languages like Node.js |
| Integration with HTML for seamless web development | Inconsistent error handling and debugging support |
| Well suited for prototyping and development speed | Lack of standardization across different implementations, leading to compatibility issues |
| Dynamic typing can lead to more flexible and adaptable code | Can result in lower performance when handling large or complex applications |
One of the best features of PHP is that it is not limited to outputting HTML. PHP can output images, PDF files, text, and even animation, all generated "on the fly".
Laravel
Laravel is a free, open-source, accessible, and reliable PHP framework based on the Model-View-Controller (MVC) pattern. Its purpose is to support web application development, simplifying and streamlining the web development process.
Laravel is easy to learn and understand, with an expressive syntax. Additional features of the framework include:
- Fast routing engine
- Multiple ways to access relational databases
- Modular packaging system with a dependency manager
- Multiple backends for cache and session storage
- Real-time event broadcasting
Symfony
Symfony is another PHP framework that includes reusable component libraries for this programming language. It is free and open-source.
Symfony is a popular toolkit used to build a wide range of web applications and other PHP projects. Its goal is to speed up development and maintenance of websites, give developers more control over their own projects, and make the process simpler and more efficient.
#3 Python
Python is one of the easiest programming languages to learn. It is also one of the most popular languages on the planet. It is used not only for web development but also for a wide variety of software development projects. One of its strengths is data science and analysis, but it finds use in many projects.
With Python, you can integrate artificial intelligence (AI) and machine learning (ML) into your websites. These features give you a number of advantages. For example, they allow you to better understand customer behavior and even create systems that learn to track and comprehend customer conversations related to a product. As you can imagine, this makes Python an excellent tool for enhancing your business appeal.
And because Python is so well suited for backend web development, it is used by major services like Spotify, Netflix, Intel, YouTube, NASA, and Instagram.
| Advantages | Disadvantages |
| Easy to learn and use with a clear syntax | Performance limitations compared to lower-level languages like C++ |
| Large and active community providing extensive libraries and support | Dynamic typing can lead to runtime errors, making debugging more difficult |
| Excellent for prototyping and development speed | May not be suitable for memory-intensive tasks or systems with high performance requirements |
| Wide range of applications, including scientific computing, data analysis, and web development | Can be slower than other languages in some cases, such as when working with large datasets |
| Well readable and maintainable code | May be less efficient than other languages for certain tasks |
One of the most important aspects of Python is its dynamic typing capability, which allows developers to build very large and complex sites whose content needs to change constantly, much more easily than with statically typed languages. In short, Python is an essential programming language to have in your arsenal.
Django
Django, called "the web framework for perfectionists with deadlines," is a free, high-level, open-source web framework for the exceptionally popular Python language. It emphasizes rapid development, security, and efficiency, and is frequently updated. Additionally, Django is highly scalable.
Primarily, Django helps developers build websites that leverage data science and databases. Components are reusable, and using the framework allows developers to write much less code and significantly speed up development.
Some of the world's leading companies and websites use Python and Django together, such as Instagram, Nextdoor, and Mozilla.
Flask
Flask is a lightweight micro-framework built with Python. This makes it easy to streamline web application development. Its features include URL routing, flexibility, and accessibility. It also has a very low learning curve, making it usable for both beginners and experienced web developers.
#4 JavaScript
JavaScript is part of virtually every web developer's toolkit due to its numerous capabilities and ways to enhance websites and web applications.
If HTML is great for creating basic, static, flat web pages, JavaScript allows you to make them modern, vibrant, and interactive. For example, with HTML and CSS you can create a basic menu on a site. But with JavaScript, you can animate that menu and even make it more user-friendly. Thus, JavaScript is not just about creating beautiful elements but also functional ones. Many of the best features found on websites come from JavaScript.
An important aspect of JavaScript is that it serves both server-side and client-side (also called back end and front end). On the client side, JavaScript creates interactive elements for site navigation and other modern features. On the server side, JavaScript includes a number of libraries and frameworks that allow developers to build any functionality, such as web applications and mobile apps.
JavaScript also allows developers to build web servers, presentations, games, smartwatch apps, and even quadcopter software.

| Dynamic and versatile, enabling a wide range of tasks | Inconsistent browser support and compatibility issues |
| Client-side execution for faster page rendering and improved user experience | Lack of standardization across different implementations, leading to compatibility issues |
| Widely supported with a large and active community | Weak typing can lead to unexpected behavior, making debugging difficult |
| Integration with HTML and CSS for seamless web development | Security vulnerabilities such as cross-site scripting (XSS) and cross-site request forgery (CSRF) |
| Interactivity allows for a wide range of dynamic UI elements | Can be less performant than other languages, especially for large or complex applications |
As we've mentioned, there are many frameworks and libraries that extend the functionality and attributes of JavaScript. Let's take a closer look at some of the most popular examples.
ReactJS
Despite being relatively new, React, maintained by Meta (formerly Facebook), is a core component of web development. This free, open-source JavaScript library is used to help develop frontends and has become the most popular frontend framework, despite actually being a library.
It can be applied in various ways, but most commonly developers use it to build user interfaces (UI) based on UI components. With the library, you can quickly build dynamic and high-performance applications.
React has a large developer community and many extensions to support the architecture.
AngularJS
AngularJS is a popular JavaScript framework and toolkit that allows developers to extend the HTML vocabulary for use in web application projects. The framework makes code more testable, maintainable, extensible, and reusable. Additionally, with AngularJS you can make your code unique.
Features of AngularJS include data binding and impressive performance. It also offers controllers and works well with other libraries.
AngularJS should not be confused with Angular, a free, open-source TypeScript-based framework for building web applications.
Vue
Vue, called the "progressive" JavaScript framework, is an open-source, Model-View-ViewModel (MVVM) frontend framework used for building user interfaces and single-page applications.
Vue is considered very accessible, incrementally adoptable, scalable, versatile, and highly performant. Depending on the usage conditions, it can act as either a framework or a library. Its rich ecosystem can scale between them.
Vue allows developers to extend HTML through HTML attributes or directives.
TypeScript
No list of web development languages would be complete without mentioning TypeScript. Developed and maintained by Microsoft, TypeScript is a superset of JavaScript created to address some of the limitations of its parent language. Primarily, it extends JavaScript by adding static typing to the programming language.
TypeScript is a free, open-source language and can be used for both frontend and backend development. Using this programming language, developers can build large-scale JavaScript applications.
Any existing JavaScript applications or programs also support TypeScript, and by using the subset, developers can apply existing JavaScript code, libraries, and other tools designed for the parent programming language. Additionally, TypeScript can run anywhere JavaScript can run.
#5 Java
Java is the most widespread language on the planet, not only due to Android development but also because of the large number of supported libraries, frameworks, APIs, and IDEs available for it.
There are several compelling reasons why many developers turn to Java for web work. For example, Java supports multithreading, meaning it can work with multiple users and threads simultaneously. This eliminates the need for developers to run multiple copies of the same code on the server, significantly increasing website response times.
Java also scales vertically and horizontally with minimal code changes. Additionally, Java is considered one of the most secure languages focused on web development. With features such as advanced authentication, cryptography, secure login mechanisms, digital signatures, ciphers, security policies, and access control, this language is hard to beat for developing secure, platform-independent web applications.
| Advantages | Disadvantages |
| Platform independence, allowing easy deployment on various operating systems | Lower performance compared to lower-level languages like C++ |
| Large and established community providing extensive libraries and support | Steep learning curve, especially for beginners |

| Wide range of applications, including desktop, mobile, and web development | Can lead to larger file sizes compared to other languages |
| Strong type checking and error handling, leading to greater code stability and security | Can be less flexible than dynamically typed languages like Python |
#6 Ruby
Ruby is an excellent programming language for web development. Although it is better known for its associated framework Ruby on Rails, it has many merits on its own. This scripting language is used for both frontend and backend web development.
Ruby is a general-purpose, user-friendly, open-source, flexible, interpreted, easy-to-learn, robust, dynamically typed, object-oriented, versatile, intuitive language that can be used to create a wide range of web products, from websites to web applications, and more. Its high-level syntax makes it especially user-friendly, as the language is very similar to English. It is often compared to the syntax of programming languages like C++, Perl, and Python.
| Advantages | Disadvantages |
| Dynamic and expressive, making it well-suited for prototyping and rapid development | Lower performance compared to other languages like C++ and Go |
| Easy to learn and use with a clear syntax | Limited support for concurrency and parallelism |
| Large and established community providing extensive libraries and support | Inconsistent error handling and debugging support |
| Well suited for rapid development with a focus on readability and maintainability | Can be less performant than other languages, especially for large or complex applications |
| Dynamic typing can lead to more flexible and adaptable code | Can be less secure than statically typed languages like Java or Go |
Ruby has other uses beyond web development—data processing, DevOps, etc.—but this is certainly its most popular use.
Ruby on Rails
A discussion of Ruby is virtually impossible without mentioning one of the world's most popular web development frameworks: Ruby on Rails, also known as RoR or simply Rails. This framework offers a vast number of libraries and features, such as easily created and accessible conventions and code generators that automatically create parts of the application.
RoR makes building sites easier. It allows you to update databases, create HTML templates, cloud storage, robust security measures, and much more.
In fact, Ruby on Rails is not only a popular framework for Ruby but also one of the most popular web frameworks overall. Perhaps that's why it is used by many large companies such as Airbnb, Bloomberg, Shopify, SlideShare, Dribbble, GitHub, Groupon, and CrunchBase.
Jekyll
Ruby on Rails is not the only tool associated with the Ruby programming language. Jekyll is a simple static site generator that can be used to create a wide range of sites, from personal projects to large organizational sites. It allows developers to convert text into static websites.
Jekyll follows this philosophy:
Jekyll does what you tell it to do—no more, no less. It doesn't try to outsmart the user by making bold assumptions, nor does it burden them with unnecessary complexity and configuration. Simply put, Jekyll stays out of your way and lets you focus on what truly matters: your content.
Some site generators have even been inspired by Jekyll, one of the most popular tools of its kind.
#7 Swift
This language is a bit different from the other programming languages in this list. After all, Swift is not usually considered a web development language. But although it is most often associated with the iOS/Apple ecosystem, meaning iOS app development, Swift, developed by Apple, is increasingly being applied in web development as well. This is particularly true when used in conjunction with Swift-based web frameworks like Perfect and Vapor, which make your efforts smoother.
Swift is a modern, clean, easy-to-read and write, intuitive, and simple-to-learn language with a concise and expressive syntax. It provides optimal performance and speed, robust security measures, and improved readability. As an open-source language, Swift is relatively young but is becoming an increasingly popular and in-demand language with a growing community.
| Advantages | Disadvantages |
| High performance, making it suitable for developing large and complex applications | Steep learning curve, especially for those unfamiliar with statically typed languages |
| Clear syntax that is easy to read and maintain | Limited support for web development, as it is primarily used for native iOS and macOS app development |
| Strong type checking and error handling, leading to greater code stability and security | Smaller community compared to other languages like Java and Python |
| Interoperability with Objective-C, allowing reuse of existing code and libraries | Can be less flexible than dynamically typed languages like Python |
| Well suited for native iOS and macOS app development, with access to a wide range of APIs and libraries | Can be less expressive than other languages, especially for complex applications |
