| description: > |
| Throws a TypeError exception if predicate is not callable. |
| info: | |
| 22.2.3.10 %TypedArray%.prototype.find (predicate [ , thisArg ] ) |
| |
| %TypedArray%.prototype.find is a distinct function that implements the same |
| algorithm as Array.prototype.find as defined in 22.1.3.8 except that the this |
| object's [[ArrayLength]] internal slot is accessed in place of performing a |
| [[Get]] of "length". The implementation of the algorithm may be optimized with |
| the knowledge that the this value is an object that has a fixed length and |
| whose integer indexed properties are not sparse. |
