TheTypedArray.of() static method creates a newtyped array from a variable number of arguments. This method is nearly the same asArray.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)

WhereTypedArray 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 newTypedArray instance.

Description

SeeArray.of() for more details. There are some subtle distinctions betweenArray.of() andTypedArray.of():

• If thethis value passed toTypedArray.of() is not a constructor,TypedArray.of() will throw aTypeError, whileArray.of() defaults to creating a newArray.
• TypedArray.of() uses[[Set]] whileArray.of() uses[[DefineOwnProperty]]. Hence, when working withProxy objects, it callshandler.set() to create new elements rather thanhandler.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 ]
