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

const int16array = Int16Array.of("10", "20", "30", "40", "50");

console.log(int16array);
// Expected output: Int16Array [10, 20, 30, 40, 50]

Syntax

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

Where TypedArray is one of:

• Int8Array
• Uint8Array
• Uint8ClampedArray
• Int16Array
• Uint16Array
• Int32Array
• Uint32Array
• Float16Array
• Float32Array
• Float64Array
• BigInt64Array
• BigUint64Array

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.of() 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()

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 ]
