+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.
