// 1 字节(1 bytes) === 8位 

// 8位 占用 1 字节(1 bytes)
// 16位 占用 2 字节(2 bytes)
// 32位 占用 4 字节(4 bytes)
// 64位 占用 8 字节(8 bytes)

// create a TypedArray with a size in bytes

const typedArray1 = new Int8Array(8);
typedArray1[0] = 32;

const typedArray2 = new Int8Array(typedArray1);
typedArray2[1] = 42;

console.log(typedArray1);
// [32, 0, 0, 0, 0, 0, 0, 0]

console.log(typedArray2);

// ⚠️ buffer 不可以直接读取, 必须创建对应的 view
