Unusual example in the inline-initialization.md about js-mythbusters

[Kikobeats]

Thanks!

The original resource was: https://www.html5rocks.com/en/tutorials/speed/v8/

The section tries to explain how v8 hidden class acts in an array initialization from a low level point of view.

I moved the high level part of the content into:
https://github.com/Kikobeats/js-mythbusters/blob/master/docs/array/preallocation.md

Also with a new example 🎉 .

Tanks, ´´´const n = 4
const array = Array(0).fill(0) // [ 0, 0, 0, 0 ]
´´´
´Array(n)´?
