| 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". |
