Go on, test this on your browser console.
You won't regret it xD xD

Ok, and now I need someone to explain that

JS sort by default stringifies all the elements so its same as sorting ['6', '-2', '2', '-7'] hence resulting in lexical sort. To do numeric just do

arr.sort((a, b) => a - b)

@meyhem Yeah, beat me to it. This is yet another example of why I find JS (and loosely typed langauges in general) bloody annoying.

"The default sort order is built upon converting the elements into strings, then comparing their sequences of UTF-16 code units values."

Also funny, try "typeof [1,2,3]"...

Spoiler JavaScript treats arrays as objects internally

@featdd which is very annoying when you're trying to verify the stucture of some JSON object. Have to use "instanceof" instead

Heh... This keeps coming back... Like learn the language stop reposting this dumb meme... You can find odd things in any language.

In python: this will happen

a = 2
b = 2
a is b # True

a = 316
b = 316
a is b # False

Why??? Because of how python deals with small ints. What should you do? LEARN THE LANGUAGE AND USE ==.

You got to be fucking kidding me. Fuck Javascript.

This is logical, suppose it does numeric sort by default, then, in order to do alphabetic sort we would have to write a function to compare strings, which might be difficult. This however, can be easily transformed to numeric sort.
