DataViews provide methods to read and write individual values from an ArrayBuffer, instead of viewing the entire thing as an array of a single type.

Here we set two bytes individually then interpret them together as a bit unsigned integer, first big-endian then little-endian. TypedArrays are a set of types providing different views into fixed-length mutable binary ArrayBuffers.
