Web/JavaScript/Reference/Global objects/TypedArray/of

The TypedArray.of() method creates a new typed array from 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:

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 Web/JavaScript/Reference/Global objects/TypedArray/Put where Array.of() uses Web/JavaScript/Reference/Global objects/TypedArray/DefineProperty. Hence, when working with Proxy objects, it calls handler.set to create new elements rather than handler.defineProperty().

Examples

Using of()

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);    // Int16Array [ 0 ]
