The byteOffset
accessor property represents the offset (in bytes) of a typed array from the start of its ArrayBuffer
.
Description
The byteOffset
property is an accessor property whose set accessor function is undefined
, meaning that you can only read this property. The value is established when a TypedArray is constructed and cannot be changed. TypedArray is one of the TypedArray objects.
Examples
Using the byteOffset
property
var buffer = new ArrayBuffer(8); var uint8 = new Uint8Array(buffer); uint8.byteOffset; // 0 (no offset specified) var uint8 = new Uint8Array(buffer, 3); uint8.byteOffset; // 3 (as specified when constructing Uint8Array)
