+description: get the integer value from fromIndex
+info: |
+  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.
+  ...
+  7. Repeat, while k < len
+    a. Let elementK be the result of ? Get(O, ! ToString(k)).
+    b. If SameValueZero(searchElement, elementK) is true, return true.
+    c. Increase k by 1.
+  8. Return false.
