Should I Use Hints and Suggestions While Coding?

Absolutely, professionals usually keep those error/warning annotations on. Relying on the compiler for feedback, especially for trivial issues, can waste valuable time. Autocompletion also saves keystrokes and jogs memory about available methods, so I say keep it on – unless you're practicing for coding interviews at a place like leetcode.

I think what you're referring to is code completion instead of AI suggestions. I keep my intellisense on and find it super helpful. TypeScript's ability to understand data shapes is a huge plus since it provides relevant suggestions as I code.

I prefer to keep hints off. They often pop up at inconvenient times, blocking my view, and I find them distracting. If I need help, I check the documentation or Stack Overflow. During my learning phase, my professor advised using an IDE without any hints or prompts, and I really believe that helped me learn better.

As a beginner too, I find it useful to start with hints and suggestions to understand the syntax better, then I'll turn them off and practice on my own. That approach has worked best for me.

I’ve tried both AI assistance and code completion. While they’re useful, I learned to type everything out without help at first. It forced me to learn by debugging each tiny mistake, which I think was invaluable. Ultimately, if the hints help you be productive, keep them. If they hinder you, definitely turn them off!
