| ECMA Section: [[ Put]] (P, V) |
| Description: |
| Array objects use a variation of the [[Put]] method used for other native |
| ECMAScript objects (section 8.6.2.2). |
| |
| Assume A is an Array object and P is a string. |
| |
| When the [[Put]] method of A is called with property P and value V, the |
| following steps are taken: |
| |
| 1. Call the [[CanPut]] method of A with name P. |
| 2. If Result(1) is false, return. |
| 3. If A doesn't have a property with name P, go to step 7. |
| 4. If P is "length", go to step 12. |
| 5. Set the value of property P of A to V. |
| 6. Go to step 8. |
| 7. Create a property with name P, set its value to V and give it empty |
| attributes. |
| 8. If P is not an array index, return. |
| 9. If A itself has a property (not an inherited property) named "length", |
| andToUint32(P) is less than the value of the length property of A, then |
| return. |
| 10. Change (or set) the value of the length property of A to ToUint32(P)+1. |
| 11. Return. |
| 12. Compute ToUint32(V). |
| 13. For every integer k that is less than the value of the length property |
| of A but not less than Result(12), if A itself has a property (not an |
| inherited property) named ToString(k), then delete that property. |
| 14. Set the value of property P of A to Result(12). |
| 15. Return. |
