WHAT DOES THIS MEAN??

For instance an ArrayBuffer instance be accessed with a Float64Array where each set of 8 bytes is interpreted as a 64-bit floating point number, or an Int32Array where each 4 bytes represents a 32bit, two's complement signed integer or a Uint8Array where each byte represents an unsigned integer between 0-255. For more info and a full list of possible typed arrays see "JavaScript Typed Arrays" by MDN web docs.
