Script Preparation code:

var enc = new TextEncoder();
var a = new Uint8Array([100 * 1024]);
for (var i; i < 100 * 1024; i++)
    a[i] = Math.floor(Math.random() * 256)
var b = enc.encode('The quick brown fox jumps over the lazy dog')
var ca = pako.gzip(a)
var cb = pako.gzip(b)
console.log(cb)
