The map function accept a source object and the definition of Source and Destination
It would be great if there is another map function that accept the source object + destination object.
My goal is instead of map source object to a new created destination, you map the source object to an existant destination object (so it will be updated)

Hi @ma-abdn thanks for the feature request. I understand this request completely and I notice it's something available in the AutoMapper .NET as well which qualifies the request a valid request. However due to reasons stated here #243 , I won't be adding this feature to @nartc/automapper and will be supporting this feature in the upcoming changes. I'll reference this in #243 and will be closing this issue.

@ma-abdn I'm reopening this to clarify. When we run mapper.someMapFn(sourceObj, destinationObj) (someMapFn name is subject to change), are you expecting destinationObj to be mutated? or someMapFn() returns a new object?

[ma-abdn]

It will more practical if the destinationObj is mutated because when dealing with an ORM if we want to merge some data to an existing object it wouldn't be possible. In other hand if we won't mutate the destinationObj we clone it just before.

@ma-abdn So we're on the same page here. Do you expect to have this functionality for mapArray as well? ( I personally don't).

[ma-abdn]

Not necessary. the map do the job.

1.0.0-beta.6 has been released. Please try it out:

map(sourceObj, destination, source, destinationObject)
mapAsync(sourceObj, destination, source, destinationObject)

Above snippet is the API to have this map mutate functionality. Please test it out and let me know. If you run into any issue, please open a new issue :)
