Script Preparation code:

c = new Uint8Array([255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255])

Tests:

Uint8Array
let stream = new Uint8Array() let a = 1000 while (a --> 0) { const buf = new Uint8Array(stream.length + c.length); buf.set(stream, 0); buf.set(c, stream.length); stream = buf; }
Array
let stream = [] let a = 1000 const push = Array.prototype.push; while (a --> 0) { push.apply(stream, c) new Uint8Array(stream) }
