+description: Get "length" uses internal ArrayLength
+info: |
+ 22.2.3.13 %TypedArray%.prototype.indexOf (searchElement [ , fromIndex ] )
+
+ %TypedArray%.prototype.indexOf is a distinct function that implements the same
+ algorithm as Array.prototype.indexOf as defined in 22.1.3.12 except that the
+ this object's [[ArrayLength]] internal slot is accessed in place of performing
+ a [[Get]] of "length".
+
+ 22.1.3.12 Array.prototype.indexOf ( searchElement [ , fromIndex ] )
+
+ ...
+ 2. Let len be ? ToLength(? Get(O, "length")).
