将 ArrayBuffer 转换为 Uint8Array

const buffer = new ArrayBuffer(64);
const arr = new Uint8Array(buffer);

const buffer = new ArrayBuffer(64);

const arr1 = new Uint8Array(buffer);
const arr2 = new Uint16Array(buffer);
const arr3 = new Uint32Array(buffer);
const arr4 = new Float32Array(buffer);
const arr5 = new Float64Array(buffer);
const arr6 = new BigInt64Array(buffer);
const arr7 = new BigUint64Array(buffer);

const buffer = new ArrayBuffer(64);
const arr = new Uint8Array(buffer, 0, 16); // 查看前 16 个字节
