I'm sorry what? I don't expect them to teach me, I just want them to tell the difference. By the way, the ones that can't say: "they told me to always use let". I'll send them to you :D. Best of luck.

I've seen plenty. If a junior dev needs to help you out of trouble every time, you know there is something wrong.
Some people just reach their limit very soon, and can hide away in some comppanies. Probaly companies where you seem to work. Other companies probably just have a higher bar, no disrespect meant.
