Hello! I'm new to JavaScript and I'm confused about which language to prefer. While JavaScript has its flexibility, TypeScript's type safety seems more appealing. Which one would you recommend? From the perspective of learning process or advantages in projects, which one makes more sense? Which one gives less headache for beginners?
JavaScript or TypeScript? Which one should you invest in?

I get that you're new to JavaScript, bro. Comparing the pros of JS and TS makes sense, but I think it's better to approach them sequentially rather than separately. First, master JS well, then decide whether you're going to do frontend or backend. JS is flexible, yeah, but that also means "you can write whatever you want," which increases the risk of making mistakes. To switch to TS, you need to have JS down pat, otherwise you'll be struggling with the language's grammar instead of its type system.
If you want type safety, you gotta invest in TS, seriously. In big projects, the type system makes it super easy to find errors, and refactoring becomes almost automatic. I always hear JS devs say, "A tiny change in a variable crashes the whole project." That’s not a typical situation in TS because the compiler warns you during the build phase. If you think it might be a headache for a beginner, think again—TS’s type system actually reduces JS’s chaotic side. Like, don’t use the "any" type; get used to type safety from the start, then figure out how to do things more comfortably.
As for projects: JS is still the most widely used language in the world, and freelance or startup projects usually go with JS. But for projects that are going to scale, switching to TS can be a matter of life and death. Even in React, instead of relying on DefinitelyTyped or React’s new type definitions for type safety, you can leverage TS’s native advantages. So invest in TS, but don’t ditch JS entirely—use the strengths of both.
Bottom line: Learn JS thoroughly first, then make the switch to TS. With TS’s type system, you reduce error rates and prepare for bigger projects. Even while learning JS, start thinking, "How can I write this in a more type-safe way?" which will make your transition to TS smoother. Honestly, projects can be done without TS, but projects built with TS tend to be more robust and easier to maintain. 🚀
I started with pure JavaScript a few years ago, and it was a constant headache with runtime errors that could have been avoided with types. I used large libraries like React or Express without issues, but as the project grew, changes in one function could break other parts without you knowing until the user reported the error. That's when I tried TypeScript in a side project... and never looked back.
At first, I was too lazy to set up the types, but once I got the hang of it, the editor (VS Code with the plugin's help) would warn me about type errors before I even ran the code. Now I develop much faster because I don't waste time debugging issues that TypeScript already caught for me. For a new project, I always start with TypeScript, though for quick prototyping or simple scripts, pure JS is still my go-to. If you're just starting now and your goal is to work in a team or on large projects, I'd recommend checking out TypeScript right away... even if you're already proficient in JS.
