The Javascript Uint32Array length property stores the element count of a typed array.
Uint32Array.length
The length property is a read only property.
The value is set when a Uint32Array is created and cannot be changed.
Using the length property
var buffer = new ArrayBuffer(8); var uint8 = new Uint32Array(buffer); console.log(uint8.length); // 8 (matches the length of the buffer)
