esid: sec-%typedarray%.prototype.includes
description: Returns false if length is 0
info: |
22.2.3.13 %TypedArray%.prototype.includes ( searchElement [ , fromIndex ] )
%TypedArray%.prototype.includes is a distinct function that implements the
same algorithm as Array.prototype.includes as defined in 22.1.3.11 except that
the this object's [[ArrayLength]] internal slot is accessed in place of
performing a [[Get]] of "length".
22.1.3.11 Array.prototype.includes ( searchElement [ , fromIndex ] )
...
2. Let len be ? ToLength(? Get(O, "length")).
3. If len is 0, return false.
