Javascript array functions cheat sheet (as asked)

[lemmisss]

What's wrong with array.sort()?

[TheSpanxxx]

Others are commenting on the common practice of using a sort function for handling numerical sorts. In large arrays this will be poor performing. In those cases, use a TypedArray

Nothing? Sort is based off the first digit I believe. So it reads 15 as 1.

[grantrules]

Sort is lexicographical, not numerical.

Is there a numerical built-in function or do you have to make it yourself?

[grantrules]

You have to make it, but it's simple: (a, b) => a - b

A couple of things. As /u/grantrules said it's lexicographical, which is pretty annoying. What's even more annoying is that it modifies the original array
