{{alias}}( obj, transform )
|
||
|
|
Maps keys from one object to a new object having the same values.
|
||
|
|
|
||
|
|
The transform function is provided three arguments:
|
||
|
|
|
||
|
|
- `key`: object key
|
||
|
|
- `value`: object value corresponding to `key`
|
||
|
|
- `obj`: the input object
|
||
|
|
|
||
|
|
The value returned by a transform function should be a value which can be
|
||
|
|
serialized as an object key.
|
||
|
|
|
||
|
|
The function only maps own properties. Hence, the function does not map
|
||
|
|
inherited properties.
|
||
|
|
|
||
|
|
The function shallow copies key values.
|
||
|
|
|
||
|
|
Key iteration order is *not* guaranteed.
|
||
|
|
|
||
|
|
