5 Best JavaScript Framework For 2021

The demands on modern web development are getting bigger and bigger and to meet them, new frameworks are created over and over again. To bring some clarity to the topic of JavaScript frameworks, the 5 best frameworks are presented here.


Angular, often also called Angular2+, is the successor to AngularJS and was released in September 2016. The focus is now on the development of a complete platform for modern web applications. The codebase was completely rewritten because the changes were so radical that an update to the new version was not enough. Angular has now been developed to meet the ever-increasing demands of modern web development.

The biggest innovation is that TypeScript is now used instead of JavaScript. Since TypeScript enables many features and a lean design that is not possible with Javascript, developers can fall back on many new tools.

However, the basic idea of ​​AngularJS still the same. Code from the old version also runs on the new version. You can continue to program with JavaScript.

One benefit of Angular is the two-way data binding. It allows developers to save time. There is no need to constantly write additional code to synchronize the model and view.
Another benefit is directives. Directives are an HTML extension that allows the developer to assign special behavior to the DOM and to generate dynamic content with HTML.
It also has a strong community. The Angular Framework is extremely popular. There are tons of courses and tutorials on the internet to help you learn it. Also, because so many people use it, it’s often easy to find a solution to almost any problem.

A disadvantage of Angular is often the performance. Dynamic applications often don’t perform particularly well and SPAs can be very impractical due to their size.



React Framework was created by Facebook for the development of user interfaces on the web and has been made available as an open-source solution since 2013. It is used to make websites dynamic by responding to changing variables and then presenting them to the user instantly. It uses the virtual DOM and thus reduces the time required for updating the page by only making necessary changes to the DOM.

The advantages of React are the reusability of components, the association of markup and methods, and that, it always renders the same HTML for the same input, just like functional programming. It also always uses the latest JavaScript features and makes the initial page load quite fast using server rendering.

A disadvantage of React is that only the view part of a frontend framework is covered, which is different from Angular, for example.


Vue.js is a client-side web-framework used to build a single page application (SPA). The most important components are a virtual DOM and the declarative rendering of single-file components. The virtual DOM can additionally be found at React and the declarative rendering at Angular. Vue.js attaches huge significance to good performance and is simple to understand, which results in a steep learning curve.

In Vue.js, HTML, CSS, and JavaScript components can be kept in separate files. Usually, you pack all of them into one file. The style does not need to be written in pure CSS, SCSS and SASS are also possible.

Vue.js offers one of the best documentation. All options that the framework offers and the corresponding best practices can be looked up here.
The framework is easy to learn since the concept behind Vue.js and its API is easy to understand. In addition, you don’t need any additional languages such as TypeScript. If you have some knowledge of HTML, CSS, and JavaScript, you can get started right away.
One of the main reasons why many developer teams rely on Vue.js is its good performance. Because of the virtual DOM, it is faster than other known frameworks.



Node.js is a framework developed in 2009 that allows the server-side implementation of JavaScript. Node.js uses a non-blocking I/O model and can as a result manage a large number of requests. This prevents overloaded servers and ensures that the implemented websites can be reached.
Node.js also works in the JavaScript Runtime Environment and therefore has properties similar to JAVA.

This framework is particularly well suited for beginners in web development, as JavaScript has already been used and learned for front-end developers. Node.js is kept very simple and developed with a focus on the essentials. The application can be expanded by packages using the Node Package Manager (npm), which is easy to use and takes care of the dependencies of modules.


Ember.js was released in 2011 and is a client-side web framework that is used for single-page applications. Similar to Angular, it is a complete framework. The given structures help the user and clearly specify which conventions must be used. This allows users to concentrate on the essentials. The developers at Ember have based on strong support from the community since its beginning, and users are actively involved in the development. Many changes are discussed publicly beforehand. In addition, it is always ensured that Ember is backward compatible for a long time. New versions do not destroy the old ones.

The disadvantage is the comparatively small community. It may be a bit too demanding for beginners and therefore harder to learn than other web frameworks.


Hopefully, we were able to provide you with a little clarity when it comes to the subject of web frameworks. These were the 5 most popular frameworks that can be found on the market today. However, there are many more and new frameworks are constantly being added. Which framework suits you best and which one is best to learn depends on what you plan to do with it. Each framework has its advantages and disadvantages and offers different options.
