While TypeScript is gaining popularity, it's unlikely that it will completely dominate over JavaScript.Why?

TypeScript is a superset of JavaScript that adds optional static typing and other features to the language. It was developed by Microsoft and has gained popularity in recent years among developers who appreciate its ability to catch bugs and improve code maintainability.

While TypeScript is gaining popularity, it's unlikely that it will completely dominate over JavaScript. There are several reasons for this:

1. JavaScript is the most widely used programming language in the world, and it has a massive developer community. It's already deeply entrenched in web development, and it's unlikely that developers will abandon it entirely.
2. TypeScript adds complexity to the development process, especially for small projects and individual developers who may not need its advanced features. JavaScript is simpler and easier to learn for beginners.
3. Many libraries and frameworks are still written in JavaScript, and while TypeScript can be used with these libraries, it requires additional configuration and setup.

That being said, TypeScript has many advantages over JavaScript, and it will likely continue to gain popularity in the future. As more developers become familiar with TypeScript and its benefits, it's possible that it will become the preferred language for larger projects and teams. However, it's unlikely that it will completely replace JavaScript anytime soon.
