TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. That means that any valid JavaScript code is also valid TypeScript code. However, TypeScript adds extra features to the language, most notably types.
The type system in TypeScript is optional, but adding types can help improve the quality of your code. For example, if you add types to your variables, you can catch errors at compile time instead of runtime. This can save you a lot of time and effort debugging your code.
TypeScript compiler can help you spot potential bugs in your code. For instance, if you try to use a variable that hasn't been initialized, the compiler will throw an error. This helps you avoid potential undefined errors at runtime.
Sometimes using TypeScript feels like a step backwards as types are somewhat limiting the dynamic nature of JavaScript and definitely may require writing a bit more code. I am not sure if it's a significant drawback but sometimes it feels uncomfortable.
Overall, TypeScript is a great tool for improving the quality of your JavaScript code. If you're looking for a way to add static types to your JavaScript code, then TypeScript is definitely worth checking out.
