Script Preparation code:
var randomArray = Array.from({ length: 1000 }, () => Math.floor(Math.random() * 256)) var randomArrayBuffer = new Uint8Array(randomArray) var randomString = new TextDecoder().decode(randomArrayBuffer)
Tests:
Array.from()
Array.from(randomArrayBuffer)
new TextDecoder()
new TextDecoder().decode(randomArrayBuffer)
new Uint8Array()
new Uint8Array(randomArray)
new TextEncoder()
new TextEncoder().encode(randomString)
