Top JavaScript trends in 2021

1-Typescript Will Keep Its Hype

Although TypeScript appeared in the distant 2012, it’s been a hype programming language in 2019-2020. TypeScript works as an extension of JavaScript that allows building complex apps both for a client and server-side execution. Many software developers enjoy TypeScript as it is strongly typed, easy to read, and simple to debug. It supports a wide range of IDEs and can be converted into JavaScript at any time. Stack Overflow ranked Typescript as one of the top three most loved programming languages. And according to GitHub statistics, it’ll continue to gain popularity together with its community expansion.

2-React.js Will Stay Popular

JavaScript offers a wide choice of frameworks for fast and effective application development. Therefore, software developers can get confused about which one suits best for a particular project. Many of them opt for React.js as it allows building robust and easy-to-scale web and mobile solutions. In Stack Overflow rating, React.js takes the top place among all the frameworks used for web development. According to nmp trends, React.js is gaining popularity among app developers, reaching 9 million downloads by November 2020. There is a great number of famous web and mobile apps built with React.js such as Facebook, Instagram, Netflix, WhatsApp, Discovery, NY Times, and many others. React.js continues to develop, adding new features in its set and attracting a wider audience. Therefore, in 2021 we expect even more apps that have React.js in their core.

3-Vue.js Will Continue to Rise

Vue.js is a recently emerged JavaScript framework. It was first released in 2014 and since then it’s been spreading rather quickly among web application developers. In 2019, Stack Overflow put it in second place among the most wanted web development frameworks, and nmp trends states that there were almost 2 million Vue.js downloads in November 2020. Xiaomi and Alibaba have earned Vue.js high regard among software developers. It’s user-friendly, highly customizable, and easy to integrate into other frameworks. With Vue.js software developers can build user interfaces and single-page apps. It’s much simpler to utilize than Angular, therefore, app developers often prefer to use Vue to build their web solutions. According to Web Technology Surveys, Vue.js use is growing. Now, it’s easy to find a Vue.js development company that is ready to provide you with effective and stable apps developed with this framework. Therefore, we expect that Vue.js is highly likely to stay with us in 2021.

4-AngularJS Will Keep Developing

AngularJS is one of the most comprehensive JavaScript frameworks that stays popular among software developers. Although it can be slow to deploy and may seem a bit bulky it offers a well-thought-out functionality with MVC architecture for building robust single-page applications. In 2019 this framework had its 8th release with a valuable set of extra features. It includes differential loading and lazy loading that make web apps faster, the ability to create web workers with the CLI that enhances web development, a new deprecation guide for developers to easily keep track of features and APIs, and much more.Stack Overflow ranges this framework 3-rd most attractive among web development frameworks. And Built With states that there are about 3.7 million sites built in Angular globally.


JavaScript is a robust and widely applicable programming language. It has a well-developed JavaScript ecosystem and it offers a wide range of tech solutions, especially in the web development field. With the further evolution of the web, we expect that new JavaScript technologies will help this programming language to keep the leading position in software development charts in 2021.
