Methods
getRandomValues
The getRandomValues method fills array with random data. Specifically, if array is an ArrayBufferView of an integer type (i.e., Int8Array, Uint8Array, Int16Array, Uint16Array, Int32Array, or Uint32Array), then all the elements of array are overwritten with cryptographically random values (see below). If array is not of an appropriate type, getRandomValues throws a TYPE_MISMATCH_ERR.
