This article introduces what are the five high-paid skills necessary for JavaScript developers in 2020. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

A developer's life can be summed up in two sentences: calculator and learning new skills. It is not easy to be a developer. They are problem solvers and continuous learners. The technology world is changing rapidly every day, and if you don't want to lag behind on this fast-changing path, you must keep learning new skills. Keep upgrading and never stop.

If you are looking for a higher-paying job or want to learn a new skill in your spare time, this article is for you. The author screened five popular skills, which are very popular with employers, who are willing to pay high salaries for developers with the following skills. If it is a newcomer in the field of software development, then this article can help you plan your time well in advance.

1. React

There are more than 50,000 jobs in the United States alone! There has been no decline in demand for React developers.

React is a JavaScript library mainly used to build amazing user interfaces in a short period of time. Other libraries have the same functionality, but React is competitive-it's super easy to use and suitable for beginners, and you can learn and start using React in 5 days.

React uses reusable components, which reduces code. It provides a large number of off-the-shelf components, you only need to download and plug-ins, very easy. Building the same thing with pure JavaScript is more difficult and time-consuming, and worst of all, your code structure is not robust.

Who is using React? WhatsApp, Facebook, Tesla, Reddit, Paypal, Twitter, Netflix and so on.

Another benefit of learning to use React is that you can soon start making native Android and IOS applications. If you have to learn a skill, learn React.

2. Node.js

Node is used to build back-end services or api. It is best suited for building highly scalable, data-intensive, and real-time applications. If you know JavaScript, this is a must-have skill, and you will soon become a true full-stack developer.

3. Git

Git is essentially a version control system. If you sum up Git in four words, it is: time travel. It is used to manage different versions of the application. Suppose you are creating an amazing application, constantly adding shiny new features, but because of a new feature, your application starts to crash. Trust me, this happens all the time.

Now you're in a stalemate, holding your head in your hands and looking at the screen. But if you have ever used Git, you can restore the changes you made that caused the application to crash with just one click. Developers always use Git, and in my life, there is no professional developer who doesn't know Git.

4. TypeScript

TypeScript is an open source language based on JavaScript that adds static type definitions. JavaScript is dynamic, and you don't have to explicitly declare the data type of a variable, you can use the same variable type to store all different data types. This will make the code unstable and difficult to debug.

But we have TypeScript. It is static, which means that you need to declare the data type during the process. This will make your code more stable, robust, readable, and error-free. People are willing to pay sky-high salaries for developers with TypeScript skills.

5. Firebase

Mark my words and learn Firebase! Imagine that you make a great website or application, and people start to visit your site quickly, and it becomes very popular. As traffic increases, you need a dedicated server, but setting up a server is really a hassle, and firebase can help you!

Firebase is an ecosystem of Google tools that can be used to create full-stack, scalable applications in Google's cloud or real-time database. It is classified as a back-end as a service (or BaaS), which gives developers the opportunity to create applications without setting up the backend.

Similar to Firebase, we have AWS, but building AWS is a headache. By comparison, Firebase is 1000 times easier to learn and set up. This is a very popular skill and people are learning it crazily.

If you are looking for a higher-paying job or want to learn new skills, then any of the above is a good choice, all you have to do is learn it!

This is the end of the five high-paid skills that JavaScript developers must have in 2020. I hope the above can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
