Uint16Array - JavaScript | MDN
Constructor
Uint16Array()-
Creates a new
Uint16Arrayobject.
Static properties
Also inherits static properties from its parent TypedArray.
Uint16Array.BYTES_PER_ELEMENT-
Returns a number value of the element size.
2in the case ofUint16Array.
Static methods
Inherits static methods from its parent TypedArray.
Instance properties
Also inherits instance properties from its parent TypedArray.
These properties are defined on Uint16Array.prototype and shared by all Uint16Array instances.
Uint16Array.prototype.BYTES_PER_ELEMENT-
Returns a number value of the element size.
2in the case of aUint16Array. Uint16Array.prototype.constructor-
The constructor function that created the instance object. For
Uint16Arrayinstances, the initial value is theUint16Arrayconstructor.
Instance methods
Inherits instance methods from its parent TypedArray.
Examples
Different ways to create a Uint16Array
js
// From a length
const uint16 = new Uint16Array(2);
uint16[0] = 42;
console.log(uint16[0]); // 42
console.log(uint16.length); // 2
console.log(uint16.BYTES_PER_ELEMENT); // 2
// From an array
const x = new Uint16Array([21, 31]);
console.log(x[1]); // 31
// From another TypedArray
const y = new Uint16Array(x);
console.log(y[0]); // 21
// From an ArrayBuffer
const buffer = new ArrayBuffer(16);
const z = new Uint16Array(buffer, 2, 4);
console.log(z.byteOffset); // 2
// From an iterable
const iterable = (function* () {
yield* [1, 2, 3];
})();
const uint16FromIterable = new Uint16Array(iterable);
console.log(uint16FromIterable);
// Uint16Array [1, 2, 3]
