JavaScript is omnipresent. Over the last two decades, it has grown to become one of the most popular coding languages that dominate web development.

In the beginning, it was bound to frontend development, but in later years it was also used in the backend or server-side development.

If you’re reading this article through social media platforms like Facebook or LinkedIn, it’s because of JavaScript, as everything falls under the umbrella of one technology.

The coding language owes its popularity to its flexibility, consistent implementation across web browsers, and its ability to deliver interactivity to webpages within the browser.

While there’s relentless competition from the likes of Java and Python, JavaScript continues to dominate web development. All these frameworks and libraries complement Agile development methodologies.

You can build a bunch of cools things with JavaScript:

As you can see from the above, this programming language wasn’t created just for web development.

A Brief History of JavaScript

JavaScript came into existence because of the infamous browser wars of the mid-1990s. In this scenario, Netscape required a lightweight scripting language for more accessible programming. So they turned to their employee, Brendan Eich, to develop it within ten days.

The result was called Mocha and later became famous as JavaScript. Eventually, AOL (America Online) bought Netscape and, over time, turned the browser code over to the Mozilla Foundation. As they say, the rest is history, as JavaScript is now a critical component of web technology and supported by the most popular web browsers.

Today, if you want to become a web developer, you should at least be familiar with this programming language. With so many JavaScript frameworks and libraries available at your fingertips, it’s hard to ignore its ability to deliver groundbreaking web experiences across browsers, devices, and platforms.

Building your web application completely with JavaScript enables seamless collaboration and a better understanding of the source code. In this scenario, even if the frontend and backend team work separately, they can come together like a well-oiled machine.

Over the years, the programming language has evolved considerably. Today, we can choose from multiple libraries, platforms, tools, and frameworks. Some of the famous ones are as follow:

AngularJS

AngularJS is an open-source framework that’s leveraged to build dynamic web apps. The structure is based on client-side technology and combines the functions of CSS (Cascading Style Sheets), HTML (Hypertext Markup Language), and JavaScript.

In this scenario, web developers can build their templates based on HTML and even extend HTML syntaxes. AngularJS also allows developers to breakdown the web app into multiple components, making it easier to code and manage.

It’s the perfect framework to bind different software components and build User Interfaces (UIs). If you’re developing a native app, for example, AngularJS allows you to use NativeScript within the template with local variables and loops.

Aurelia

Aurelia is essentially a collection of open-source JavaScript modules, and JavaScript development projects often use it as a standalone solution. Aurelia follows an ECMAScript standard, so you can quickly build web and mobile apps.

Aurelia is both advanced and highly user-friendly. As a “next-generation UI framework,” you can start building without specifying controllers of view models.

As it’s highly modular, you can develop apps without forcing the use of specific predefined rules or paradigms. This means that you can easily swap components in and out during the development cycle.

EmberJS

EmberJS is a popular open-source framework among developers who build large scale mobile and web apps. An excellent example of EmberJS is the Apple Music mobile app that’s completely Ember-based.

EmberJS is ideal for Single-Page Applications, large web apps, and building a complete development stack. This perfectness is because its handlebars layout and backend architecture are designed to allow developers to write advanced HTML tags.

It also makes it easy for them to understand complex functionalities through user-friendly Application Programming Interfaces (APIs) that come with the framework. EmberJS is also better suited for client-side development than both Mithril and Polymer.

NodeJS

NodeJS is a server-side framework and a JavaScript Engine of the Google Chrome browser. Networking and server-side applications in runtime environments are built using this open-source framework.

NodeJS is also leveraged to build backend services and APIs. Operating systems like Linux, macOS, and Microsoft Windows also use these apps.

Because it works with a single-threaded event loop, NodeJS can handle multiple asynchronous requests seamlessly. It’s the perfect solution to develop real-time collaborative web applications.

ReactJS

ReactJS is a JavaScript framework and library that’s popular among developers who build UIs for Single-Page Applications. When you build mobile and web apps with ReactJS, it’s easy to handle all the view layers of the app.

It also makes it easy to develop reusable UI components. It’s the go-to solution for robust, high-performing enterprise applications.

The UIs of both Facebook and Instagram, for example, are excellent examples of ReactJS at work. ReactJS was developed by Facebook to make web development simple, scalable, and fast.

ReactJS is also used with other JavaScript libraries and popular open-source PHP frameworks like Laravel. With the help of JSX extensions, syntaxes are short and straightforward.

Svelte

Svelte is a frontend component-based development framework that’s similar to both ReactJS and VueJS. The primary difference is that Svelte does all the work in compiled steps during the development cycle.

ReactJS and VueJS, on the other hand, conduct the bulk of the work within the browser. While this incarnation of a JavaScript framework is still relatively new, it’s already the go-to framework of GoDaddy and the New York Times.

VueJS

VueJS is a lightweight progressive JavaScript library and framework that’s perfect for highly responsive and interactive websites and apps. It aims to make UI development highly organized. It operates on a Virtual DOM and leverages standard technologies to build web apps.

VueJS uses plain HTML-based templates and single-file components. It also allows developers to code in CSS within the framework. When you build advanced single-page web apps with VueJS, dependencies of components during rendering are tracked automatically by it.

In this scenario, whenever a component needs re-rendering, VueJS informs the system about the pending state changes.

So if you’re thinking about building a new website, it’s essential to think of JavaScript. Gone are the days of static websites that aren’t responsive or interactive. Static websites are also not optimized across mobile devices, so it’s far from ideal.

When you build with the help of JavaScript frameworks, your online presence can take the form of a website or a web app, and cater to the changing needs of the audience, both effectively and seamlessly.
