| Behavior when `hint` is "number" and neither first nor second try are callable. |
| info: | |
| 1. Let O be the this value. |
| 2. If Type(O) is not Object, throw a TypeError exception. |
| 3. If hint is the String value "string" or the String value "default", then |
| a. Let tryFirst be "string". |
| 4. Else if hint is the String value "number", then |
| a. Let tryFirst be "number". |
| 5. Else, throw a TypeError exception. |
| 6. Return OrdinaryToPrimitive(O, tryFirst). |
