+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 ] )
+
+  ...
+  4. Let n be ? ToInteger(fromIndex). (If fromIndex is undefined, this step
+  produces the value 0.)
+  5. If n ≥ 0, then
+    a. Let k be n.
+  6. Else n < 0,
+    a. Let k be len + n.
+    b. If k < 0, let k be 0.
+  7. Repeat, while k < len
+    ...
+  8. Return false.
