You may want to look into asm.js, working with 32bit signed integers using |0 everywhere, the typed arrays, the safe integer range of JS numbers, etc. Integers are usefull even in js!

The terrifying bit is, in these days of iterable data structures you maybe *could* manage to avoid using actual arrays for a very long time.

fun fact: I was really into trying to learn to program when I was 9 years old so I was always going to the library and trying to learn about computers but I was a tiny dyslexic baby so I was always going up to the computer search and typing "POGRAMMING" and it would just be like DONK ERROR

Using the raw power of highly unsafe, string-based programming I have successfully avoided any and all explicit use of arrays. I will never use strict; in Perl! There is nothing in a bash script that I won't exec. I have no rules and eschew all decorum!

I've dabbled a little in python for fun... you know making the ultimate open world MMORPG from scratch until giving up after a few weeks and an actually (mostly) working viewport :D But I don't use arrays. Only lists of lists, tuples of tuples, sets of lists... dictionaries of tuples...

I'm not sure I've ever gotten an actual raise in my whole career? I specifically remember that one year I put in some extra effort and overtime to save 10 years of data and about 50 million dollars of work and at the end they gave me a raise that was lower than the rate of inflation that year

“Yes, I’ve instantiated several arrays. I’ve pushed to them. I’ve had limited experience in shifting arrays, but plenty of solid pop experience. I’ve always wanted to learn about sorting so I’m excited for this role.”

Removes a confusion with phased arrays. But could be to filter out folks who have only ever done vanilla Python or something like that.

My favorite story of those "list skills you have" systems was when my dad was updating his LinkedIn... They have that system where you can endorse your connections on their skills, so it asked him "does Guido van Rossum know Python?" to prompt an endorsement.
