Beyond React?

Description

A lot of students ask me what to learn beyond React. Actually React is more then enough to get a job.
But if you add TypeScript, NextJS and GraphQL to it you will get a higher package or even a senior role.
Now, most companies wants an stable product and also want to use the cutting edge tech in React ecosystem.
All these three tech were released some time back and made it into a lot of production sites.
The benefit of TypeScript is that it catches error even before you save in VS Code.
It seems to be more work, but helps a lot in saving precious debugging time in a React project.
It is been used in a lot of companies and the scratch projects or the projects been changed to React, uses it in most companies.
NextJS is an interesting tech which bring Server Side Rendering to React. The code is mostly same as it's a ReactJS framework.
But it brings Image optimization, SEO into React and finally the code runs on server and not on client browser like React.
Now, this saves those micro seconds and also beneficial for Web-apps which are becoming big. Again all companies love this tech.
Now GraphQL is a specification which challenges the REST specification. It is mainly the way we write backend code.
We need to write frontend code also because it is a different way to interact with graphql endpoint.
The benefit been the load, as from client we can only ask for a subset of data and get it. It is not possible in REST, where we have to change the backend code for the same.
