Examples
Different ways to create an Int8Array
js
// From a length
const int8 = new Int8Array(2);
int8[0] = 42;
console.log(int8[0]); // 42
console.log(int8.length); // 2
console.log(int8.BYTES_PER_ELEMENT); // 1
// From an array
const x = new Int8Array([21, 31]);
console.log(x[1]); // 31
// From another TypedArray
const y = new Int8Array(x);
console.log(y[0]); // 21
// From an ArrayBuffer
const buffer = new ArrayBuffer(8);
const z = new Int8Array(buffer, 1, 4);
console.log(z.byteOffset); // 1
// From an iterable
const iterable = (function* () {
yield* [1, 2, 3];
})();
const int8FromIterable = new Int8Array(iterable);
console.log(int8FromIterable);
// Int8Array [1, 2, 3]
