Appreciate it man thanks for watching 🙏

[@sruthisivakumar5682]

Clear difference sited out when and where to use it

[@MrNaizon]

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.

Thank You sir! Please what theme do you use in VSCode?

[@dcode-software]

It's my theme. Search for "dcode" on VS Code Extensions Marketplace

U explain this stuff very very well You should do udemy courses

[@dcode-software]

Thank you. I actually do have a few Udemy courses but maybe I should do some more 😎

[@TomasMisura]

i am old school guy, still iterating using old but good for :) But I personally feel that i would need modernize myself :)

[@dcode-software]

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

[@TomasMisura]

@@dcode-software OK, I'll do it.

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.
