| 5. If thisArg was supplied, let T be thisArg; else let T be undefined. |
| 6. Let entries be the List that is the value of M’s [[MapData]] internal slot. |
| 7. Repeat for each Record {[[key]], [[value]]} e that is an element of |
| entries, in original key insertion order |
| a. If e.[[key]] is not empty, then |
| i. Let funcResult be Call(callbackfn, T, «e.[[value]], e.[[key]], M»). |
