9 Web Technologies Every Web Developer Should Know

Developing an application or website, even one as simple as a bakery website, typically comes down to knowing three core languages: JavaScript, CSS, and HTML. And while this may sound quite complex, once you learn what you're doing, understanding web technologies and how they work becomes significantly easier.

If you want to expand your knowledge and skills in web development, enrolling in web developer courses can provide structured learning and a deep understanding of the core concepts, programming languages, and frameworks used in the field.

Don't get discouraged if it doesn't come to you right away. You might need more time, preparation, and patience to dive deeper into the subject, but in the end, you'll understand it all.

We present you an introduction to web technologies and a list of the latest web technologies, hoping that this will make your task a little easier. So, let's take a look.

What Does the Term "Web Technology" Mean?

You've probably heard the term "web development technologies," but have you ever thought about what it actually means?

Since computers cannot communicate with each other the way humans do, they need codes. Web technologies are markup languages like HTML, XML, XHTML, and multimedia packages used by computers to communicate.

1. Browsers

Browsers request information and then display it in a way we understand. Think of them as the interpreters of the Internet. Here are the most popular ones:

• Google Chrome – currently the most popular browser, developed by Google.
• Safari – Apple's browser.
• Firefox – an open-source browser maintained by the Mozilla Foundation.
• Internet Explorer – Microsoft's browser.

2. HTML and CSS

HTML is one of the first topics you need to learn. Thanks to HTML, web browsers know what to display after receiving a request. If you want to better understand how HTML works, you also need to know what CSS is.

CSS stands for Cascading Style Sheets and describes how HTML elements should be displayed on the screen. If you go through enough tutorials, you'll soon be able to create text effects, page transitions, image hover effects, and more using CSS.

3. Web Development Frameworks

Web development frameworks are starter sets of elements that developers can use to avoid performing simple or repetitive tasks and get straight to work.

Angular

Angular is one of the newest web technologies, created specifically for developing dynamic web applications. With this framework, you can easily build front-end applications without relying on other frameworks or plugins.

Features include well-designed templates, MVC architecture, code generation, code splitting, and more. All expressions are code fragments enclosed in curly braces and do not use loops or conditional statements.

Ruby on Rails

Ruby on Rails is a server-side web development technology that makes application development much simpler and faster. A distinguishing feature of this framework is code reusability, along with other great capabilities that help you get the job done quickly.

Popular sites built with Ruby include Basecamp, Ask.fm, GitHub, 500px, and many others.

YII

Yii is an open-source framework for developing web applications, built on PHP5. It is performance-optimized and comes with excellent tools for debugging and testing applications. Another plus is that it is quite simple and easy to use.

Meteor JS

Meteor JS is written in Node.js and allows you to build real-time web applications for various platforms. This framework for creating simple personal websites truly stands out.

It is an open-source isomorphic JavaScript web framework, which significantly reduces web page load times. The JavaScript stack also allows you to achieve the same results with fewer lines of code than usual.

Express.js

Express.js, built on Node.js, is a web application development network that is ideal for those who need to develop applications and APIs as quickly as possible. Many great features are provided via plugins.

Zend

Zend is an open-source PHP framework focused on building more secure and reliable web applications and services. It was one of the first enterprise-level MVC frameworks, appearing before super-hits like Laravel or Symfony, and many popular PHP engines, such as Magento, were built on Zend.

Today, Zend continues to evolve actively, and although it may be less popular than its open-source counterparts, it is an excellent solution for large-scale PHP applications.

Django

Django is one of the most popular frameworks, written in Python and built on the MVC architecture. Its simplicity greatly eases the application development process.

Django significantly simplifies the use of Python and provides many tools that make a web developer's life easier—such as ORM, models, Django admin, templates, and more.

Laravel

Laravel is a PHP framework that is perfect for small websites. It boasts many useful features, including MVC support, object-oriented libraries, Artisan, authorization techniques, database migrations, and more. It is currently one of the most community-supported and developed frameworks, and given that PHP has one of the largest communities, Laravel is an excellent tool for supporting both small sites and large B2B portals that handle millions of transactions daily.

4. Programming Languages

As we explained, since computers do not use human-like languages, they need a different way to communicate. Here are some of the most popular programming languages:

• JavaScript – used by all web browsers, Meteor, and many other frameworks.
• CoffeeScript – a "dialect" of JavaScript. It is considered simpler but compiles back to JavaScript.
• Python – used in the Django framework, as well as in most mathematical computations.
• Ruby – used in the Ruby on Rails framework.
• PHP – used in WordPress to create the WYSIWYG editors that everyone uses today. It is also used by Facebook, Wikipedia, and other large sites.
• Go – a newer language designed for speed.
• Swift – Apple's newest programming language.
• Java – used in Android and many desktop applications.

Now, let's talk about the most popular ones in a bit more detail.

JavaScript

According to the annual StackOverflow survey, JavaScript is the most popular programming language, with 62.5% of respondents stating they use it.

Ruby

Developers love Ruby – and for all the right reasons. Designed to be friendly and easy to use, it's no wonder it's often called "the programmer's best friend."

What you can expect from Ruby is shorter and more readable code. Unfortunately, this sometimes means lower efficiency compared to other programming languages – but it also means higher productivity.

If you're just starting out in web development, Ruby is an excellent choice for a first programming language. Well-written Ruby code can be almost as readable as a sentence in plain English.

But the real reason most people use Ruby is the popular Ruby on Rails framework, which we mentioned earlier in this text. The high productivity achieved with Rails makes it a common choice for startups aiming for a quick launch.

Elixir

The Elixir language emerged in 2011 and gained popularity almost immediately. It was inspired by the Erlang language, developed by Ericsson back in the 80s. The creator of Elixir, José Valim, said he really liked Erlang but noticed some aspects that could be improved.

Scala

Scala stands for Scalable Language and is one of many attempts to "rewrite Java." It compiles to run on the Java Virtual Machine (JVM). It's safe to say that this programming language has proven quite successful, given that companies like LinkedIn, Twitter, and The Guardian use it in their codebases. Scala is known as a complex language but one worth learning.

5. Protocols

Instructions for transferring information between computers and devices are called protocols.

HTTP
This protocol allows every website to reach the browser. The protocol requests the site from the Google server and then receives the site's HTML, CSS, and JavaScript as a response.

DDP
Uses WebSockets to create a persistent connection between the client and server. As a result, site updates occur in real time without needing to refresh the browser.

REST
This protocol, primarily used for APIs, has standard GET, POST, and PUT methods that allow information exchange between applications.

6. API

API (Application Programming Interface) allows other developers to use some functions of an application without sharing the code.

Endpoints are exposed by developers, and API access can be controlled via an API key. Examples of well-made APIs include those created by Facebook, Twitter, and Google for their web services.

7. Data Formats

Data is stored in a structure called a data format.

• JSON (JavaScript Object Notation) – a syntax for storing and exchanging data (similar to XML). It is currently becoming the most popular data format.
• XML – mainly used in Microsoft systems and was once the most popular data format.
• CSV – data formatted with commas; for example, Excel data.

8. Client (or Client Side)

Every user of an application is called a client. Clients can be computers, mobile devices, tablets, etc. Typically, multiple clients interact with the same application stored on the server.

9. Server (or Server Side)

Application code is usually stored on the server. Clients make requests to servers. After gathering the requested information, servers respond to those requests.

Frequently Asked Questions About Web Technologies

1. What is HTML and what is its role in web development?
HTML (HyperText Markup Language) is a markup language used to create web pages and applications. It gives material on a web page a specific structure, including headings, paragraphs, graphics, and links.

The building blocks of the Internet are HTML, which is crucial for creating and displaying web content. Combined with other web technologies like CSS and JavaScript, HTML allows programmers to create dynamic, rich web applications with engaging user interfaces.

2. What is CSS and how is it used in web design?
CSS (Cascading Style Sheets) is a language for creating style sheets that describe how HTML or XML documents should be displayed. It allows developers to create more complex and aesthetically pleasing web layouts by separating the structural design of a web page from its visual presentation.

The ability to change the appearance of text, colors, backgrounds, borders, and other visual elements makes CSS a powerful tool for creating aesthetically pleasing and functional web pages.

3. What is JavaScript and how is it used in web development?
Web applications can be made dynamic and interactive using the JavaScript programming language. It is primarily used to add interactivity to web pages and create web programs that respond to user input. JavaScript is useful for many purposes, including multimedia effects, animation, and form validation. It is a crucial component of modern web development and a powerful tool for creating engaging user experiences.

4. What is responsive design and why is it important?
A web design technology called responsive design ensures that a website adapts to the screen size on which it is displayed. This means the site will work and look great on all platforms, including desktop computers and mobile devices.

Responsive design is very important for ensuring usability and accessibility of a site, given the prevalence of mobile devices.

Additionally, a responsive website provides a better experience because less zooming and scrolling is needed to access the content.

5. What is a web framework and how does it facilitate web application development?
A software environment called a web framework offers a standardized method for building and deploying web applications. It often includes a set of best practices, frameworks, and tools that make creating, testing, and maintaining online applications easier.

With web frameworks, developers can focus on building high-level functions and capabilities, abstracting away many low-level aspects of web development.

Ruby on Rails, Django, and React are a few well-known web frameworks.

6. What is a content management system (CMS) and what are some popular examples?
Users can develop, manage, and publish digital materials such as websites, blogs, and online stores using a content management system (CMS), which is a software application.

A CMS often has an intuitive user interface, web page design templates, and tools for managing content, such as text and photos. WordPress, Drupal, and Joomla are a few well-known CMS platforms.

7. What is a web server and how does it work?
A web server is software that uses the Internet to deliver web pages and other content to clients.

A user requests a web page, the web server processes the request, retrieves the necessary information from a database or file system, and sends it back to the client as an HTTP response.

Web servers support multiple programming languages and web technologies, such as PHP, Ruby, and Python.

8. What is the difference between client-side and server-side scripting?
Client-side scripting describes the execution of code, often in the form of JavaScript, in the user's web browser. A web page can be made more interactive by using client-side scripting to modify the DOM, validate form data, and add interactivity.

On the other hand, server-side scripting describes the use of code that is executed on the web server before being delivered to the client. To process form data, access databases, and generate dynamic content, server-side scripts are often used.

While server-side scripting is more secure and capable of handling more complex processes, client-side scripting is faster and more responsive.

9. What are some common web development tools and software?
Web developers have access to a wide range of software and tools, including text editors, web servers, development environments, and version control programs.

Visual Studio Code and Sublime Text are a few of the most common text editors. Code completion and debugging are additional features of IDEs such as Eclipse, NetBeans, and IntelliJ IDEA.

Online content is hosted and served using web servers like Apache, Nginx, and IIS. Source code changes are managed using version control tools like Git and SVN.

10. What is web hosting and how do you choose the right provider?
With hosting, individuals and organizations can host their websites on the Internet.

Among the pricing plans offered by hosting companies are shared hosting, virtual private servers (VPS), and dedicated hosting servers. When choosing a hosting company, factors such as uptime, performance, support, and security should be considered.

Additionally, when choosing a hosting provider, it's important to understand the differences between WordPress hosting and traditional hosting, and to assess whether your site needs specialized WordPress hosting features or if traditional hosting is sufficient.

Furthermore, you need to consider the specific requirements of the site, such as bandwidth and storage space, and choose a hosting package that meets those requirements.
