Examples
Different ways to create an Int16Array
js
// From a length
const int16 = new Int16Array(2);
int16[0] = 42;
console.log(int16[0]); // 42
console.log(int16.length); // 2
console.log(int16.BYTES_PER_ELEMENT); // 2
// From an array
const x = new Int16Array([21, 31]);
console.log(x[1]); // 31
// From another TypedArray
const y = new Int16Array(x);
console.log(y[0]); // 21
// From an ArrayBuffer
const buffer = new ArrayBuffer(16);
const z = new Int16Array(buffer, 2, 4);
console.log(z.byteOffset); // 2
// From an iterable
const iterable = (function* () {
yield* [1, 2, 3];
})();
const int16FromIterable = new Int16Array(iterable);
console.log(int16FromIterable);
// Int16Array [1, 2, 3]
