Are we seeing a backlash against TypeScript lately? While the benefits of static typing in our projects seem undeniable, some developers argue that it slows us down and unnecessarily complicates even 'simple' JavaScript projects. What do you think? What are TypeScript's advantages, and in which cases might other approaches make more sense? How much does your stance change depending on the size and needs of your projects?
TypeScript: Unnecessary complexity or the language of the future?

I was thinking the same thing recently when I tried TypeScript on a small project. At first, it was tough switching from JavaScript, but now I see how the type errors during development have already saved me hours of debugging. That said, for quick scripts or very simple things, the setup still feels overkill to me.
What I see is that TypeScript isn’t for every project, but when used right, the juice is absolutely worth it. In my day-to-day with React + TS, I catch bugs at compile time that would’ve flown right by me in plain JS—stuff like mismatched props or functions receiving the wrong number of arguments. And don’t even get me started on autocompletion and refactoring; with plain JS, you’re basically dead in the water.
That said, where I’ve seen it lose steam is in small, throwaway scripts where you know it won’t grow. For example, a 50-line CSV processor had me tangled in types until I bailed and went with JSDoc. In those cases—no team, no future maintenance—TypeScript can feel like overkill. The key is to weigh it: if the project’s big, shared, or long-term, TS saves you hours of debugging. If it’s a one-off, JS + JSDoc or even TS without strict mode is plenty.
