| 22.2.3.25 %TypedArray%.prototype.some ( callbackfn [ , thisArg ] ) |
| |
| %TypedArray%.prototype.some is a distinct function that implements the same |
| algorithm as Array.prototype.some as defined in 22.1.3.24 except that the this |
| object's [[ArrayLength]] internal slot is accessed in place of performing a |
| [[Get]] of "length". |

| ... |
| 4. If thisArg was supplied, let T be thisArg; else let T be undefined. |
| ... |
| 6. Repeat, while k < len |
| ... |
| c. If kPresent is true, then |
| ... |
| ii. Let testResult be ToBoolean(? Call(callbackfn, T, « kValue, k, O »)). |
