More specifically, you have to keep an eye on the latest JavaScript development trends. This compelling knowledge will help you create high-performing, engaging, and responsive web products. 

Top JavaScript Trends in 2021

What are the most prominent JavaScript trends you should go for in 2021? Let’s find out by discussing it further!

Vue Is Emerging Further

The last year was marked with the long-expected launch of Vue.js - 3.0. There is a lot to mention, like the boosted applications’ performance and smaller bundle sizes. Also, we saw a significant enhancement in TypeScript support.

Following is the list of key Vue advancements that will affect JavaScript trends in 2021 and further.

• Enhanced performance;
• TypeScript integration;
• Layered modules;
• Compatibility for Large-scale projects.

React Is Thriving

The popularity of React has been emerging over the past few years and doesn’t show signs of stopping. This library came into being in 2011. At that time, Facebook required a particular tool to maintain rapidly growing traffic for their services. So they launched a solution called FaxJS. It can be found as the initial stage prototype for React.

In 2013, Facebook turned React into an open-source project. Thanks to the hardworking maintainers, React has become the center of JavaScript LibrariesToday many household names actively use it. Pinterest, Netflix, and Reddit are among them. That’s why it has become crucial to hire experienced React.JS developers while building comprehensive apps following this JavaScript Trend. 

TypeScript’s Rapid Spurt

TypeScript is well-known as a superset of JavaScript. Microsoft launched it in 2012 with the ideology of offering support for optional types that JavaScript lacks.

The main benefits of using TypeScript are the following:

• Quick bug detection
• Optional static typing
• Enhanced support for big-scale projects
• Widespread adoption
• Easy onboarding.

Be aware that you have to compile the TypeScript code into the usual JavaScript code. Only then can it be executed by your web browsers. This drawback of TypeScript can lead to crucial delays for minor projects. Therefore, you should prefer JavaScript in such cases.

GraphQL Taking A Grip On Data Management

GraphQL is a comprehensive product introduced by Facebook. It was launched in 2015 as a robust data management tool. Its flexible syntax facilitates the querying of information from both the client-side and server-side. Nowadays, it is prominently used by popular entities like Shopify, Coursera. And Github.

Following are the benefits of using GraphQL and make it an outstanding JavaScript trend for 2021.

• Customized request;
• Fast data retrieval;
• Enhanced query efficiency.

Web Components Can Be Taken As The Building Blocks

Nowadays, it has become quite common to use web components in any famous framework or plain JS.

What makes these frameworks so popular? The following specifications are the answer to this question.

• Shadow DOM allows you to encapsulate DOM subtrees to the web elements.
• Custom Elements helps you create new autonomous HTML tags with entirely customizable functioning.
• HTML Template enables you to build markup fragments that don’t affect the page load instantaneously.
• ES Modules define how to add JS modules and reuse them in several JS files.

Following are the advantages of implementing web components as a promising JavaScript Trend in 2021

• Mobile improvement;
• Encapsulation and reusability;
• Flexibility and interoperability.

Gradual Momentum for Svelte

Being an open-source front-end framework, Svelte rests upon component-based architecture. Its initial version, released in 2016, was written in JS. However, the third edition uses TypeScript instead. It was launched in 2019. It sparked interest among product owners. 

The main benefits of Svelte are its importance.

• Enhanced performance;
• Built-in reactiveness;
• Readable and Compact syntax.

AngularJS Will Keep Building

AngularJS is one of the most extensive JavaScript frameworks that stays on the top priority among the community of product owners. Although it may seem a bit bulky and can be slow to deploy, it offers well-thought-out functionality with MVC architecture for developing robust single-page apps.

The Rising of Component-based Architecture

Component-based architecture focuses on reducing the design into separate functional or logical elements. These elements embody neatly defined communication interfaces such as methods, events, and properties.

Following are the key benefits of component-based architecture:

• Easy deployment;
• Simplified development process;
• Reduced cost.

So why should you implement a component-based approach? By opting for components, you make it possible to use the code written by your team for another project or by the whole open-source community.

Wrapping Up

We hope the JavaScript Trends in this list will help you build quality products for your full-fledged enterprise or startup. The best way to understand the benefits of these trends is to implement them in your development projects. The more you keep an eye on the trends, the more aware you become of which features should be there in your product. In addition, these trends set by the community of product owners and developers can enhance the development practices of your team to build efficient software.
