guest271314 Let's say you have a TypedArray such as var u = Uint8Array.of(49, 48, 48, 48) and you know those values in hexidecimal will produce an integer parseInt(new TextDecoder().decode(u), 16) // 4096. How can that 4096 be derived without converting to a string, using DataView or other methods to get the integer?

PhoenixIllusion case insensitive ascii-to-hex could be brute forced via:

function hexFromArray(a) {

function getChunkedData(u8) {
  let crlfIndex = 0;
  let chunkLength = "";
  let chunkBuffer = new Uint8Array(0);
  crlfIndex = u8.findIndex((v, k, array) => v === 13 && array[k + 1] === 10);
  if (crlfIndex > -1) {
    // https://gist.github.com/guest271314/d6e932154e11fffb75fd7d1a4b25f4f5
    for (let i = 0; i < crlfIndex; i++) {
      const hex = u8[i];
      let intVal = hex & 0xF;
