  22.2.3.7 %TypedArray%.prototype.every ( callbackfn [ , thisArg ] )

  %TypedArray%.prototype.every is a distinct function that implements the same
  algorithm as Array.prototype.every as defined in 22.1.3.5 except that the this
  object's [[ArrayLength]] internal slot is accessed in place of performing a
  [[Get]] of "length".

  22.1.3.5 Array.prototype.every ( callbackfn [ , thisArg ] )

  ...
  7. Return true.
