TypeScript is not expected to replace JavaScript but rather serves as a powerful extension, particularly beneficial for complex projects.Why not always use TypeScript?
One thing that many beginners do not understand about TypeScript is that it does not guarantee type-correctness at runtime. Your TypeScript code might be fully typed and the compiler ensures you that everything must be correct… but at runtime you still get errors because your variables might be of the wrong types!Big projects are ditching TypeScript… why?
Why is TypeScript not popular?
TypeScript might be considered the worst programming language by some due to its strict typing system, which can add complexity and verbosity to code. It also requires a learning curve for those already familiar with JavaScript, and its compile step can slow down the development process.Can TypeScript do everything JavaScript can?

Why use any TypeScript?
The any type is an escape hatch—it allows you to effectively turn off Typescript's type checking. Sometimes, there just isn't a good way to tell Typescript what you are doing, so you use any to work around that.Why we should use TypeScript instead of JavaScript?
Advantages of TypeScript over JavaScriptTooling Support: TypeScript offers superior tooling support with features like code navigation, intelligent code completion, and refactoring tools, improving developer productivity.
Which is faster TS or JS?
