that ‘map’ method is slower than ‘forEach’. Take in consideration when working with big sets of data, because it can block main thread for a longer time and affect a website performance.

Yeah just add "map" to your code if you're doing array transformations.

Careful though, these are NOT the same things! Whereas forEach and map perform a function on each item of your data, a for loop does what the name implies, looping over your data. Consequently, the behavior WILL be different, for instance when fetching data, etc.
