Awesome post! I have to make the subtle point of the performance difference when you use certain approaches though.

let multipliedByTwo = arr.map((el) => timesTwo(el));


let multipliedByTwo = arr.map((el) => timesTwo);
creates extra unnecessary function around a function. It can be more of a hit when you nest function definitions inside of a callback, but that's a subject for a different post altogether! Great work here!


Absolutely true. And given that I was trying to show identical code I struggled over whether to include that one. Thanks for noting it. I likely should have of the original post!
