Most efficient way to create a zero filled JavaScript array?

Question

What is the most efficient way to create an arbitrary length zero filled array in JavaScript?

Answer 1

The way I usually do it (and is amazing fast) is using Uint8Array. For example, creating a zero filled vector of 1M elements:

  var zeroFilled = [].slice.apply(new Uint8Array(1000000))

I'm a Linux user and always have worked for me, but once a friend using a Mac had some non-zero elements. I thought his machine was malfunctioning, but still here's the safest way we found to fix it:

  var zeroFilled = [].slice.apply(new Uint8Array(new Array(1000000))

Missing the most important test (at least for me): the Node.js one. I suspect it close to Chrome benchmark.
