Do I really need to use TypeScript?

No you don’t.

It’s an option for you, if you think you need it.

TypeScript is an extra layer to JavaScript to help ensure type safety.

“Type Safety? What?”

JavaScript is dynamically typed, which means that you won’t know if there are type related problems with your code until runtime.

TypeScript is checked for type safety as you write it. This is at least what happens when you use VSCode and you have TypeScript installed.
