Uint8Array

The Uint8Array() constructor creates a typed array of 8-bit unsigned integers. The contents are initialized to 0. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

Syntax

new Uint8Array()
new Uint8Array(length)
new Uint8Array(typedArray)
new Uint8Array(object)

new Uint8Array(buffer)
new Uint8Array(buffer, byteOffset)
new Uint8Array(buffer, byteOffset, length)

Note: Uint8Array() can only be constructed with new. Attempting to call it without new throws a TypeError.

Parameters

See TypedArray.
