Although TypeScript was released in 2012, it became the programming language of hype in 2019-2020. TypeScript acts as an extension to JavaScript, allowing the creation of complex applications for client-side and server-side execution. Many software developers prefer TypeScript because it is highly standardized, easy to read, and simple to debug. It supports a wide range of IDEs and can convert to JavaScript at any time.

Stack Overflow ranked Typescript as one of the top three programming languages. And according to GitHub statistics, its popularity continues to grow as the community expands.

#2 React.js remains popular

JavaScript offers a wide range of frameworks for fast and efficient application development, leaving software developers confused about which one is best suited for a particular project. Many of them choose React.js because it allows them to create robust and easily scalable web and mobile solutions.

According to Stack Overflow's rating, React.js is the number one framework for web development. According to map trends, React.js is growing in popularity among app developers, with 9 million downloads by November 2020.

Many famous web and mobile apps have built using React.js, including Facebook, Instagram, Netflix, WhatsApp, Discovery, NY Times, and many more. React.js is constantly growing, adding new features and attracting a wider audience. As a result, we expect to see even more applications based on React.js in 2021.

#3 Vue.js will continue to rise

Vue.js is a JavaScript framework that was recently released. It was first released in 2014 and had been spreading quite rapidly among web application developers since then. Stack Overflow ranked it as the second most popular web development framework in 2019, and trends reported nearly 2 million Vue. J downloads in November 2020.

Xiaomi and Alibaba highly value Vue.js among software developers. It is user-friendly, highly customizable, and easily integrates with other frameworks. With Vue.js, software developers can create user interfaces and single-page applications. It is much easier to use than Angular, so application developers often prefer to use Vue to build their web solutions.

According to Web Technology Surveys, the use of Vue.js is growing. It is now easy to find a Vue.js development company ready to provide you with efficient and stable applications developed with this framework. Therefore, we expect that Vue.js will most likely stay with us in 2021.

#4 AngularJS will continue to grow

AngularJS is one of the most comprehensive JavaScript frameworks that remains popular among software developers. Although it can be slow to deploy and may seem cumbersome, it offers thought-out sound features with MVC architecture to build robust single-page applications.

In 2019, the eighth edition of this framework release with valuable extra features.

 It included differential loading and lazy loading to make web applications faster, the ability to create web workers with the CLI to improve web development, a new deprecation guide for developers to more easily track the use of functions and APIs, and much more.

Stack Overflow ranks this framework as the 3rd most attractive among web development frameworks. And it was Built With claims that there are about 3.7 million sites built in Angular worldwide.

#5 PWAs are becoming more and more popular

PWAs are becoming more and more popular, and more companies are willing to develop them. According to Statista, 24% of e-commerce companies plan to invest in PWAs, while 11% are already using them.

Progressive Web Apps (PWAs) are available on wireless devices such as mobile phones and tablets. They work like traditional websites, although they behave like mobile apps. Software developers use web-building technologies such as HTML, CSS, and JavaScript to develop PWAs.

PWAs have several advantages. They are cross-platform, adapt quickly to different screen sizes, update automatically, work offline, create secure connections for data exchange, and many other features.

Some companies have already tried PWAs and were satisfied with the results: Uber, Twitter, and Pinterest are among them. They have managed to attract more customers, increase revenue from monthly visits, and much more.

#6 SPAs are gaining ground.

Single-page applications (SPAs) are the new way to browse websites on wireless gadgets. SPAs allow users to browse web pages without reloading them, resulting in a more dynamic experience.

To create SPAs, web developers use standard web technologies such as JavaScript, HTML, CSS, AngularJS, React.js, or Vue.js. The most famous examples of SPAs are LinkedIn, Airbnb, Facebook, Gmail, and others.

Other benefits of SPAs that will make them trendy in 2021 are

• Extended battery life;

• Improved user experience;

• Fast site navigation;

• Improved caching;

• Ease of development and maintenance.

#7 AMP increases download speeds.

According to Web Technology Surveys, AMP sites are growing in popularity. The trend continues to grow, and we expect AMP's influence to grow even more by 2021.

Google developed the Accelerated Mobile Pages technology to make downloading websites faster. To do this, Google provides software developers with ready-to-use, unmodifiable JavaScript code, as well as HTML and CSS frameworks. Google restricts the use of customized JavaScript in AMP pages, as it often slows downloading speed.

Several sites already use AMP, including Twitter, The Guardian, CNBC, Gizmodo, and others.

In addition to fast loading pages, AMP has a few other advantages:

• SEO improvement, as Google prefers AMP pages;

• users spend more time on the page because they don't have to wait long for the page to load;

• Improved monetization due to better usability of images and banners in the HTML code;

• easier to be noticed as Google presents pages in the Google Search Top Stories carousel, resulting in AMP content appearing first in Google search.
