TypedArray.of()

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

Try it

Syntax

js

TypedArray.of()
TypedArray.of(element1)
TypedArray.of(element1, element2)
TypedArray.of(element1, element2, /* …, */ elementN)

Where TypedArray is one of:

Parameters

element1, …, elementN

Elements used to create the typed array.

Return value

A new TypedArray instance.

Description

See Array.of() for more details. There are some subtle distinctions between Array.of() and TypedArray.of():

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

Examples

Using of()

js

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 ]
