readUint8() with for loop
const length = 1000; const arrayBuffer = new ArrayBuffer(length); const array = new Uint8Array(arrayBuffer); for (let i = 0; i < length; i++) { array[i] = 22; } const dataView = new DataView(arrayBuffer); const resultArray = []; for (let i = 0; i < length; i++) { const value = dataView.getUint8(i); resultArray.push(Boolean(value)); }
slice() with map()
const length = 1000; const arrayBuffer = new ArrayBuffer(length); const array = new Uint8Array(arrayBuffer); for (let i = 0; i < length; i++) { array[i] = 22; } const dataView = new DataView(arrayBuffer); const transferArray = new Uint8Array(dataView); const resultArray = [...transferArray].map(Boolean);
slice() with Array.from()
const length = 1000; const arrayBuffer = new ArrayBuffer(length); const array = new Uint8Array(arrayBuffer); for (let i = 0; i < length; i++) { array[i] = 22; } const dataView = new DataView(arrayBuffer); const transferArray = new Uint8Array(dataView); const resultArray = Array.from(transferArray, Boolean);
