Is JavaScript Trending, Top 7 JavaScript Trends In 2021

js2021

JavaScript is a powerful and widely used programming language. It has a well-developed JavaScript ecosystem and offers a wide range of technical solutions, especially for web development.

JavaScript remains one of the most popular and researched programming languages in 2020, with the Stack Overflow survey shows JavaScript topping the list as the most popular technology. Nearly 70% of professional developers worldwide use this programming language. Its popularity drives by its simplicity and the wide range of applications developed in JavaScript, from web development to non-browser environments.

In the coming year, JavaScript will continue to grow in popularity, and JavaScript-based development services will remain high. This article looks at the seven key JavaScript trends you should focus on and adopt in 2021 and explain why you should implement them in your projects.

 1. TypeScript is keeping up with expectations

Include Typescript way back in 2012, but in 2019-2020 it’s a hot programming language.TypeScript acts as an extension of JavaScript and can use for both complex client-side and server-side programming. Can build applications. Many software developers prefer TypeScript because it is enormously easy to read and easy to debug. TypeScript supports a wide range of IDEs and can converts to JavaScript at any time.

Stack Overflow ranks TypeScript as one of the top three most popular programming languages. And, according to GitHub statistics, its popularity will continue to grow as the community expands.

2. React.js will continue to grow in popularity

JavaScript offers a wide range of frameworks for fast and efficient app development. As a result, software developers are sometimes confused about the best framework for a given project. Many such developers choose React.js, which allows them to build robust and easily scalable web and mobile solutions.

According to Stack Overflow reviews, React.js is the number one framework for web development. According to map trends, React.js is increasingly popular among app developers and will reach 9 million downloads by November 2020. Many famous web and mobile apps have built using React.js, such as Facebook, Instagram, Netflix, WhatsApp, Discovery, NY Times, etc. React.js are constantly evolving and adding new features to attract more and more people. It is attracting more and more people. So in 2021, we can expect to see even more apps with React.js at their core.

3. The continued growth of Vue.js

Vue.js is a recently released JavaScript framework that has been spreading pretty quickly among web app developers since its launch in 2014. In 2019, Stack Overflow ranked it the second most requested web development framework, and according to map trends, nearly 2 million people downloaded Vue.js in November 2020.

Xiaomi and Alibaba highly value Vue.js among software developers. It’s easy to use, highly customizable and integrates easily with other frameworks. Software developers can use Vue.js to build user interfaces and single-page apps, and because it’s much easier to use than Angular, app developers often use Vue to build web solutions.

According to Web Technology Surveys, Vue.js usage is growing. Today, it’s easy to find a Vue.js development company ready to develop efficient and stable apps on this framework. Therefore, we predict that Vue.js will likely be with us in 2021.

4. AngularJS will continue to evolve.

AngularJS is one of the most versatile JavaScript frameworks that are enduringly popular among developers. While it can be slow to implement and seem cumbersome, it offers well-thought-out features with an MVC architecture to build robust single-page applications.

In 2019, the framework saw its eighth release with a valuable set of additional features, including differential loading and lazy loading to make web apps faster. The ability to create web workers using the CLI to streamline web development, a new deprecation guide for developers to track features and APIs easily, and much more

Stack Overflow ranks this framework as the third most attractive web development framework. A Built With claims that there are about 3.7 million sites built in Angular worldwide.

5. PWAs are becoming increasingly popular.

Progressive Web Apps are growing in demand, and more and more companies want to develop them. According to Statista, 24% of e-commerce companies plan to invest in PWAs, and 11% are already using them.

Progressive Web Apps are available on wireless gadgets such as mobile phones and tablets. They function like regular websites, although they behave like mobile apps. To create PWAs, developers use web building technologies such as HTML, CSS, and JavaScript.

Progressive Web Apps (PWAs) have many advantages. They are cross-platform, quickly adapt to different gadget screen sizes, update automatically, work offline, establish secure connections for data exchange, and many other features.

Some companies have already tried PWAs and were happy with the results; they are Uber, Twitter, Pinterest. They have been able to attract more customers, increase revenue from monthly visits, and more.

6. SPAs are growing.

Single page apps (SPAs) are a new way to navigate websites on wireless gadgets. SPAs allow users to interact with websites without reloading, giving users a more dynamic experience. To build SPAs, 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 advantages of SPAs that make them a trend in 2021 are:

  1. Extended battery life;
  2. Improved user experience;
  3. Faster site navigation;
  4. Better caching;
  5. Easy to develop and maintain.

7. AMP will contribute to increased download speeds.

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

Google developed accelerated Mobile Pages technology to make web pages download faster. To do this, Google provides developers with ready-made, unmodified JavaScript code, and HTML and CSS frameworks. Google limits custom JavaScript on AMP pages because it is often a factor in slowing downloading speeds.

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

In addition to fast page loading, AMP has several other benefits:

  1. Better SEO, as Google prioritizes AMP pages;
  2. Users spend more time on the site because they don’t wait too long for the page to load;
  3. Better monetization due to better use of images and banners in the HTML code;
  4. Easier to find because Google shows pages in the Top Stories tab in Google search, so AMP content is shown first in Google search.

Conclusion

As the web continues to evolve, we expect that new JavaScript technologies will help this programming language maintain its position at the top of the software development rankings in 2021
