This is not applicable and useless; why would anybody write this instead of the clear readable parseInt.
If you want to tell people about this just say it but don't say don't use parseInt!

Good old days. ☺ I have used this trick many years ago, before nodejs was even a thing. The performance benefit seems minute but collectively, on an operation intensive project, there will be noticeable improvement.

what if i want to parse 'a' as a number and add it to another vairable ?

let a = '10'
let b = 20

b += +a ?
b = b + +a ?

this is very confusing.

Be a team player. Write parseInt() instead, someone has to read your code one day

This is just bad advice. You are sacrificing readability for a language hack.
