Yea. Another huge thing to me is the slice operator. I use it
for a lot of stuff and it is consistent for strings and other
arrays. (well, utf issues aside, but D's rule there is simple
enough to remember too)
Arrayviews ("slices") are available as a type so you can do it
like this:
a = new Uint32Array([7,2,3,6]) // a is [7, 2, 3, 6]
b = a.subarray(1,3) // b reference [2, 3]
b[0] = 8 // now a is [7, 8, 3, 6]
a.set([5,9], 2) // now a is [7,8,5,9]
Destructuring is coming too. So you can destructure arrays as if
they are tuples. E.g.:
var a,b;
[a,b] = [2,4]
[a,b] = [b,a]
I think it might work in TypeScript or some of the other
compilers already.
