TypedArray.of

The TypedArray.of() method creates a new typed array with a variable number of arguments. This method is nearly the same as Array.of().

Syntax

TypedArray.of(element0[, element1[, ...[, elementN]]])

where TypedArray is one of:

Int8Array
Uint8Array
Uint8ClampedArray
Int16Array
Uint16Array
Int32Array
Uint32Array
Float32Array
Float64Array

Parameters

elementN

Elements of which to create the typed array.

Return value

A new TypedArray instance.

Description

Some subtle distinctions between Array.of() and TypedArray.of():

• If the this value passed to TypedArray.of is not a constructor, TypedArray.of will throw a TypeError, where Array.of defaults to creating a new Array.
• TypedArray.of uses [[Put]] where Array.of uses [[DefineProperty]]. Hence, when working with Proxy objects, it calls handler.set to create new elements rather than handler.defineProperty.

Examples

Uint8Array.of(1);            // Uint8Array [ 1 ]
Int8Array.of('1', '2', '3'); // Int8Array [ 1, 2, 3 ]
Float32Array.of(1, 2, 3);    // Float32Array [ 1, 2, 3 ]
Int16Array.of(undefined);    // IntArray [ 0 ]
