Memory shouldn't make a difference.

a = Array(1e7); for ( let i=0; i<1e7; i++ ) a[i] = i; takes ~50 ms on my machine.

Array.from(..) takes ( wait for it - literally :P ) ~3300 ms.

For 1e3 elements, it's ~.2 ms vs. ~1 ms.

Hi Chrono. How can I see random tests on C#? Console.Write doesnt work.

print(arr) seems to work fine for me (in Python). If you used javascript try console.log instead.

Doesn't print work?
