The Javascript Uint8ClampedArray length property stores the element count of a typed array.
Uint8ClampedArray.length
The length property is a read only property.
The value is set when a Uint8ClampedArray is created and cannot be changed.
Using the length property
var buffer = new ArrayBuffer(8); var uint8 = new Uint8ClampedArray(buffer); console.log(uint8.length); // 8 (matches the length of the buffer) var uint8 = new Uint8ClampedArray(buffer, 1, 5); console.log(uint8.length); // 5 (as specified when constructing the Uint8ClampedArray) var uint8 = new Uint8ClampedArray(buffer, 2); console.log(uint8.length); // 6 (due to the offset of the constructed Uint8ClampedArray)
