As technology advances, JavaScript has developed into a major programming language in the web development world. It’s the language of choice for developers when creating websites, web applications, and mobile applications. JavaScript continues to grow in popularity, impacting how we interact with the world around us.
This article seeks to explore the available JavaScript frameworks and their individual advantages and disadvantages. It will also discuss the pros and cons of using a JavaScript framework and what steps are needed to develop an application using any of them.
What Is JavaScript and How Does It Work?
JavaScript is a programming language developed by Netscape in 1995. It is traditionally used to develop client-side web applications and run them within web browsers. In this context, web pages are considered documents that the web browser reads and displays for the user. By adding JavaScript to a page, the page can become interactive, allowing animations, visual effects, or other dynamic content to be added to the page.
JavaScript is an interpreted language, so it does not need to be compiled before it can be used. Instead, a JavaScript interpreter is used to read the code and then execute it. When a user visits a web page with JavaScript, this interpreter will read the code, parse it, and execute it line by line.
Popular Javascript Frameworks
To take advantage of JavaScript’s full power, developers often turn to frameworks—tools designed to help them build JavaScript applications quickly and efficiently. Here is a list of the most popular Javascript frameworks:
AngularJS
AngularJS is a front-end web application framework created by Google in 2009. It is designed to make web development easier by providing a framework that simplifies the development process. It uses HTML and JavaScript to structure pages and interaction with the user. It also has a built-in template system of custom HTML tags, providing the ability to quickly and easily produce dynamic content with minimal coding.
ReactJS
ReactJS is a library created by Facebook in 2013 that is used to create user interfaces for web and mobile applications. Its goal is to create components of code that are re-usable throughout an application, reducing the need for large amounts of code. React leverages AJAX calls to communicate with servers and manipulate data, allowing developers to create highly responsive applications quickly.
Vue.js
Vue.js is an open-source front-end framework created in 2014 by Evan You. It’s designed to be used as the view layer of MVC (Model-View-Controller) architecture. Vue.js uses an HTML-based template syntax and two-way data binding to create dynamic applications with minimal code. It also has an optional build toolchain that provides support for ES2015 modules, language abstractions, and hot module replacement.
Node.js
Node.js is an open-source server-side JavaScript environment created by Ryan Dahl in 2009. It was created from Chromium’s runtime engine and JavaScript programming language, providing the ability to write server-side code in JavaScript. Node.js is used for building real-time applications, such as chats and dashboard applications. It has an event-driven architecture that allows developers to quickly process multiple events simultaneously.
Ember.js
Ember.js is an open-source web application framework created by Yehuda Katz in 2007. It provides developers with a specialized syntax for creating rich user interfaces. It takes care of most of the underlying implementation details, enabling developers to concentrate on the application’s functionality instead of reinventing the wheel every time they need a new feature.
Backbone.js is an open-source JavaScript framework released in 2010 by Jeremy Ashkenas. It provides structure for building single-page web applications, allowing developers to focus on coding instead of managing the page structure. Backbone.js offers Model-View-Controller (MVC) architecture which c helps developers maintain a clean separation between the data layer, user interface layer and business logic.
MeteorJS is an open-source JavaScript framework built on Node.js and designed specifically for creating full-stack web applications. It contains all the necessary libraries and utilities needed for a full-stack application, making it much easier and quicker to launch a full application. MeteorJS also has an integrated testing framework that makes it easy to add automated tests.
Polymer
Polymer is a library created by Google in 2013 for building highly interactive web applications and websites. Polymer is built on top of Web Components, allowing developers to create components by combining HTML, CSS, and JavaScript into pre-defined elements, allowing for fast development of interactive websites.
