Discussion on "I can't write a JavaScript for loop, and it does not matter"

I've been using JavaScript daily for 7 years, and I'm not able to remember the syntax of a JavaScript for loop. Despite this fact, I'm a rather successful freelance developer. Recently I even had the awesome opportunity to work for Facebook, as the D...

Thank you for this article! I'm pleased to see I'm not the only one to not remember stuff considered basic. My favorite: finding out I've already upvoted the SO answer I'm looking for :)

Thanks 😉

Or finding that you actually answered the question you ask for 10 years ago 😅 as I've got 70k on Stackoverflow it actually happens 😄

This is one of the most stupid article I began to read (could not read until the end, too painfull).

There is a lot of uses for indexed array access (including, for instance, comparing or using two correlated arrays with only one loop, instead of a nested loop).

Using a function call requires stack manipulation, context switching, etc. Is slow as hell. Thousands of times slow (but don't trust me, do a test, as any scientific method requires).

You are just a bad programmer and hashnode just became a Medium competitor (in article quality).

I can indeed write for loops with indices if perf matters, but in most cases it's premature optimisation.

Do you always prematurely optimize? Do you feel a for loop is always the best solution for lists of size 10?

Enhanced for loop was introduced in Java 5, not Java 6.

Ah good point. I guess my school teachers were using Java4 :D

This is a brilliant read! Absolute quality.

Nice write up. :-) Please tag it with JavaScript tag for better reach.

Thanks, forgot the tags :)
