Script Preparation code:

const enc = new TextEncoder();
var a = new Uint8Array([...Array(1000000).keys()]);
var b = enc.encode('The quick brown fox jumps over the lazy dog')
var ca = pako.deflate(a)
var cb = pako.deflate(b)

Tests:

zip pako a
pako.deflate(a)
zip fflate a
fflate.zlibSync(a)
zip pako b
pako.deflate(b)
zip fflate b
fflate.zlibSync(b)
unzip pako a
pako.inflate(ca);
unzip fflate a
fflate.unzlibSync(ca);
unzip pako b
pako.inflate(cb)
unzip fflate b
fflate.unzlibSync(cb)
