| 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". |

| ... |
| 4. Let n be ? ToInteger(fromIndex). (If fromIndex is undefined, this step |
| produces the value 0.) |
