Sets are NOT arrays. Learn some comp sci nigga.

>In mathematics, a set is a well-defined collection of distinct objects
Sets are distinct. Arrays are not.

Also, sets are not indexed. Also, sets do not have a size limit.

Nah, sets and arrays are two different things. Arrays are ORDERED and indexed by numbers and are fixed in size and do not have to have unique values.

Sets have no size limit and are NOT indexed by indices and are NOT ordered and all values must be unique.

The biggest difference is ordering, index lookup, and uniqueness.

An array of 3 1 2 means 3 first, 1 second, 2 third.

A set of 1 2 3 and a set of 3 2 1 are the SAME thing. Order doesn't matter.

Anything with a finite description can be given as an array (of characters). Much of the time this array is useless for doing anything with.

Go ahead, give the set of continuous functions from the Klein bottle to itself as an array, and then do something meaningful with this representation.

/sci/ fags are truly fucking retarded.

Btw, I make $160K making JS/TS/React apps and guess what, they all use arrays. So, fuck your bottle, fuck your mother, and most especially, fuck you. :)

but you can just say arrays are sets modulo set equality (they have the same elements irrespective of order) instead of reflexive equality (same elements in same order)

The following is a set
1, 2, 3

The following is not a set
2, 2, 3

Therefore, arrays cannot always be sets.

A number isn't actually an object of set theory a priori. And mostly when some object of set theory is identified with a number, then that object is itself a set of numbers.

actually sets are "smaller" than classes (so they have a "size"), see that famous paradox of the set containing all sets.
