  22.2.3.25 %TypedArray%.prototype.some ( callbackfn [ , thisArg ] )

  %TypedArray%.prototype.some is a distinct function that implements the same
  algorithm as Array.prototype.some as defined in 22.1.3.24 except that the this
  object's [[ArrayLength]] internal slot is accessed in place of performing a
  [[Get]] of "length".

  22.1.3.24 Array.prototype.some ( callbackfn [ , thisArg ] )

  ...
  7. Return true.
