What is a JavaScript Framework?

Any web developer is familiar with HTML, CSS, and JavaScript. HTML is a hypertext markup language that gives structure to our websites, CSS gives style and JavaScript makes our websites interactive and responsive. The next step is to explore JavaScript Frameworks.

JavaScript Frameworks are a group of JavaScript frameworks that give programmers pre-written JavaScript code to utilize for common programming tasks and aids in the development of web applications and web pages. Frameworks are not a necessity and strong web applications can also be built without using these frameworks; however, these frameworks provide developers with a template that handles common programming patterns. Let me put it another way; if you are a web developer and you are building websites and web applications, wouldn’t it be better to use pre-written codes instead of writing the same program from scratch. The framework does the same thing by providing you with an existing feature set that you can use and build websites or web applications.

By following JavaScript frameworks, rules and guidelines anyone can make a complex web application that is faster and more efficient than developing a web app from scratch. The JavaScript framework rules and guidelines help us structure and organize our code. We can think of it as a pottery wheel that rotates and we have to work with it to make different shapes and sizes of pots, plates, bowls, etc but the pottery wheel cannot make a house with it as we need a different framework to work for that.

Let’s move on to another topic: framework and a library difference. The difference between these two is very blurry however let me simplify it for you a little bit that a framework organizes your web application or website having a full toolset whereas a JavaScript library is pre-written JavaScript code that provides some features and they are less about shaping our application.

MVC (Model View Controller)

JavaScript frameworks are built around the MVC design architecture so that we will have structure as well as adaptability in software development. The model view controller is just a software design architecture that divides programming logic into three different interconnected parts. The first part is the Model which handles application data and provides dynamic data structure hence becoming the central component of the Model view controller. The view part handles all the code that represents the user interface and the controller part acts as the interpreter by accepting some input and converting that input into commands for the view or model part.

JavaScript Frameworks

JavaScript has by far the most frameworks than any other programming language and since it is used both for the client-side as well as the server-side there are different popular frameworks available for each of them. We’ll go over both the front-end and back-end frameworks for JavaScript.

Front End Frameworks

A front-end framework is a development platform for your front end and usually includes a method for creating files, associating data with DOM elements, styling components, and making AJAX queries, and some of them are discussed below:


Angular is by far one of the most popular front-end frameworks of javascript which was developed by Google and is supported by both Google as well as Microsoft and is a free and open-source enterprise-level JS framework that aids developers in the creation of large and sophisticated corporate applications.


React is created by Facebook and is basically a JavaScript library but it is discussed in terms of Framework as React is very efficient and flexible. React best features include predictable code and easily debugged code which is used to create interactive user interfaces. The best thing about React is that it divides its code into components hence blocks of code written once can be reused for different parts of that application. Suppose you designed a button in a webpage, and then you need to use that same button somewhere else in the application, you don’t have to write the code from scratch but just import the button component where you want to reuse the button.


Vue.js is a JavaScript framework that is used to develop user interfaces for creating complex and single web pages or applications. Vue framework helps developers by making integration with other existing projects as well as other libraries very easy.

Back-end Frameworks

Backend frameworks are collections of server-side computer languages that aid in the development of a website’s backend structure and offer pre-built components for building dynamic web applications. Using frameworks gives developers an advantage by removing the requirement to construct and configure everything from scratch. Some of the back-end frameworks are discussed below:


Express js is one of the most popular and widely used Node js frameworks for server-side applications by giving developers flexibility and by being lightweight as well as the minimalist framework. Express js features include high-performance speed as well as it gives developers a wide range of HTTP utilities.


Next. js is a minimalistic framework that gives developers an edge on creating static web pages/applications as well as server-side rendering using the popular React Js framework. As demonstrated on the Facebook scale, Next js is a quick, dependable live-editing experience.


JavaScript Frameworks are collections of JavaScript libraries having pre-written Js code used for routine programming features and makes our web pages interactive. The JavaScript frameworks make JavaScript very easy to use as well as are adaptable in web application designing. There are multiple JS frameworks each having its own features and solutions to different problems.

In this article, we discussed what JavaScript Framework is and went through a few JavaScript frameworks including front-end and back-end frameworks. Frameworks make our lives easy and when choosing a Js framework always learn about your project requirements first and then choose the framework based on those requirements.
