Editor to share with you what the main development trend of JavaScript in 2021 is, I believe most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

1. React is booming

Can you guess the leading JavaScript framework for 2020? Yes, it's a reaction. No surprises.

The library was released in 2011. At that time, Facebook needed a specific tool to maintain the fast-growing traffic of their services. So they introduced a solution called faxjs. It can be seen as an early prototype of React.

In 2013, Facebook was transformed into an open source project. The maintainer's efforts made the center of the JavaScript developer library respond. Today, many family names actively use it. Netflix,pinterest and reddit are among them.

In 2020, React NPM packages are likely to be downloaded more than Vue.js, which is the second most popular JavaScript framework. Take a look at the chart below to see the adoption trend of the JavaScript framework.

Our team is an avid fan of the React framework. We can certainly say that 2021 will be a good year for response developers. Check out best practices and tools to maintain relevance.

2. Vue is developing further.

2020 marks the long-term release of Vue.js-3.0. What does it bring? We should improve the performance of promoted applications and smaller bundling sizes. In addition, we have made significant improvements in Typescript support.

Let's list the key JavaScript advances that will affect 2021 and further affect VUE trends:

Improve performanc

Support large-scale projects

TypeScript integration

Layered module.

3. Rapid application of Questcript

Typescript is called a subset of JavaScript. Microsoft introduced its idea in 2012 to support options that JS lacks.

Microsoft's technical solution is limited to type key items. Nevertheless, a recent JS survey shows that the language is the most commonly used technology there.

The main advantages of type standards are as follows:

Optional static type

Rapid detection

Improved support for large projects

Widely adopted

It's easy to transfer.

These are the main reasons for Typescript's second most popular language. We have a correct prediction that its popularity will develop further in 2021.

Speaking of Typescript, we can't just mention its shortcomings.

Note that you need to compile the TypeScript code into regular JavaScript code. Only in this way can it be executed by the browser. According to small projects, it may lead to significant delays in small projects. We recommend using JavaScript in these cases.

4. Web components can be regarded as the building blocks of the network.

Today, it is a common practice to use Web components or even plain JavaScript in any popular framework.

What makes them so popular? The following specifications will help you answer this question:

Custom elements help developers build new autonomous HTML tags with fully customizable behavior.

Shadow DOM enables the encoder to encapsulate DOM subtrees into Web elements.

The ES module defines how to include the JavaScript module and reuse it in other JS documents.

The HTML template allows you to create markup fragments that do not affect page loading by instantiation at run time.

Let's outline the benefits of implementing Web components as a prominent JavaScript trend in 2021:

Reusability and encapsulation

Mobile Enhancement

Interoperability and flexibility.

5. GraphQL is being applied to data management

GraphQL is another product launched by Facebook. It was launched in 2015 as a data management tool. Its flexible syntax helps to query data from both the server and the client. These days it is actively used by big names, including Coursera,Shopify and Github.

In 2020, GraphQL has the highest interest in all the technologies that programmers know. 89.6% of programmers have heard of the language or want to learn it.

Let's discuss the benefits of an excellent JavaScript trend for GraphQL in 2021.

Faster data retrieval

Custom request

Improve query efficiency.

6. Component-based architecture is on the rise

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

The main advantages of a component-based architecture are as follows:

Easy deployment

Reduce the cost

A simplified development process.

So why do you implement a component-based approach? By selecting components, you can use parts of the code that the team wrote for another project or for the entire open source community.

7. Svelte is gaining momentum

Svelte is a free open source front-end framework based on component architecture. Its first version, launched in 2016, was written in JavaScript. However, the third version uses type annotations. It was released in 2019. It aroused the interest of developers. Currently, 15% of JavaScript developers use this framework and are very satisfied with it.

Let's take a look at the main advantages of Svelte and see what makes it so special.

Built-in React

Improve performanc

Compact and readable grammar.

Currently, Svelte cannot compete with the most popular JavaScript framework. Nevertheless, the latest trends indicate that its use will continue to grow.
