2020 can be described as the revolutionary year for JavaScript frameworks, as we saw huge development of these frameworks and the beginning of their use among the masses.

Read more to keep yourself updated with the frameworks that are predicted to rise.

What is JavaScript Framework?

JavaScript is a programming language that is commonly used for the development of moderate applications. It is lightweight and supported by the majority of the browsers we use in our daily life. It supports both Object-Oriented programming(OOPs) and Procedural programming. Hence, it is used commonly for making web pages with the client-side script to interact with the user and make the web pages effective and concise.


It is nothing but a large part of a code that you can apply to your code to some problem that you are facing in a specific domain. It can be used by providing “callbacks“.

Advantages of JavaScript Frameworks

  • It has strong community support which keeps it always updated.
  • Possess extensions that help in debugging components.
  • Plenty of third party component support.
  • The efficiency of the code increases.
  • It is free and open to use for all.
  • Possesses the ability to keep the user interface in synchronization with the state of the system.

2020 being such a great year for JS, what does 2021 have in store for us??

Now that we have discussed the JavaScript Frameworks, let us check out the rising frameworks in 2021:



Angular is an open-source application framework, which works on TypeScript. It has been developed and maintained by Google and released back in 2016 when there weren’t many framework applications. Due to this, it was the most widely used software back then. To date, it has 6 versions- Version 2, version 4, Version 5, Version 6, Version 7, Version 8. Although its position has decreased because of the launch of new frameworks, it is still one of the top 3 most widely used frameworks around the world and companies prefer to hire people who have the knowledge of Angular,


  • Very reliable due to the support from Google.
  • A large number of tools for performing actions.
  • The quality of programming is high.
  • Good quality code generation.


  • It requires a lot of knowledge about the software before working on it.
  • It consumes a large amount of energy.
  • Poor optimization of problem-solving, leading to low productivity.



The current leader of all the framework fields, React is developed by Facebook developers. It was launched completely in November last year while a prototype was launched back in 2013. It is based on reusable components. Most of the companies use it as their primary framework tool. It was the fastest-growing application in the framework field last year and is supposed to maintain that growth in 2021 too. Most of the developers speak in the same voice that React is easy to learn given that you have basic knowledge of JavaScript.


  • Highly Adjustable.
  • Files composed are of small size.
  • Has a good JavaScript library.
  • Good stability.


  • Documentation is not very fluent.
  • Proper study is required to use the extra tools to use them for coding.



Vue is an Open-source JavaScript-based framework that is mostly used for building software interface for the users. It was released in February 2014. Its creator, Evan You, worked for Google and used Angular. He noticed how heavy the framework was and when he created Vue, he made sure that it would be lighter than Angular. At 20KB in size, it has the smallest size among all frameworks. Due to this, it is rapidly growing but it still has a long way to the top.


  • Fast Installation.
  • Ridiculously small size.
  • The study of components before coding is not required.
  • Simple to use.
  • It offers a lot of extensions to code with.
  • Blends with other programming languages without any problem.


  • A small community of users and developers.
  • Less amount of tools.
  • Highly fluctuating.



Meteor is a free and open-source Framework based in JavaScript written in Node. It has the ability to produce cross-platform code among different platforms. It was released in 2012 and had a good growth rate but its growth was stalled by frameworks like Angular and React.


  • Generates Cross-Platform code.
  • Easy to use.


  • Lack of user and developer community.

5.Svelte JavaScript

Svelte Javascript

Svelte is a framework that is used for creating code. Its main developer is Richard Harris. Due to its small size, its speed gets increased many folds.


  • Small Size.
  • Fast speed of operation.
  • It can exist separately with the code which was created by it.
  • Easy to use.
  • It requires less amount of memory.


  • Very small community.
  • Limited functions and tools.

6. Ionic


Ionic framework is a complete open-source Software Development Kit (SDK) for hybrid mobile development created by Max Spiery, Ben Sperry, and Adam Bradley of Drifty Co. in 2013. The pilot version was built on AngularJS and Apache Cordova. However, the latest release was re-built as a set of Web Components


  • It is supported by all the platforms.
  • It allows the user to build applications.
  • Big companies like PayPal use it.
  • The Ionic framework provides a command-line interface (CLI) to create projects.


  • This framework requires time to learn it.
  • It is a little complex compared to other frameworks.
  • It is not very secure when compared to other frameworks.
  • Specific plugins have to be developed.



Ember is an open-source JavaScript Framework based on Model-view-view-Model (MVVM). It is used by websites like Apple, Twitch, Groupon, and Linkedin. It is owned by Tilde Incorporated and was launched in 2011


  • It contains built-in testing tools.
  • Good community support from users and developers.
  • It is capable of giving high performance.
  • Its performance is good


  • It requires a lot of study for doing coding on it.
  • Even after a large community, development speed is slow.


The frameworks mentioned above are the ones to be watched for the year 2021. But that does not mean the other frameworks are bad. It just means that they require a few modifications in their setup. Who knows they might be the one to watch out next year. But out of the frameworks mentioned, the ones to be observed with a close eye would be Angular, React and Vue.
