Like can't you use either "==" or "===" in Typescript but the first one can sometimes do a type coercion that can occasionally have unexpected effects? If I remember right it is a warning but not an error, a programmer who is clearing up warnings will stay out of trouble but if you weren't clearing warnings it would make a difference if you had a "==" or "===".

One thing that makes you a better dev as opposed to a worse dev is your habits, especially when it is something obscure where the compiler and IDE don't have your back.
