Add sortObject function

[aleclarson]

Create a new object whose keys are sorted according to a given callback that compares object entries.

const newObject = sortObject(
  input,
  ([key1, value1], [key2, value2]) => {
    return key1 > key2 ? -1 : 1
  }
)

What do you think about sortObjectKeys or sortObjectEntries? Sounds clearer to me.

[aleclarson]

How about sortObjectByEntries?

We could also have sortObjectByKeys which only passes in the key to the comparator function. The comparator could even be optional, which would use the same default behavior as Array sort.

Oh, I think it's not possible to do it according to spec

[aleclarson]

Sorry, what's not possible? You mean making it type-safe?

[Minhir]

For each own property key P of O that is an integer index, in ascending numeric index order

It will override order of the one provided by comparator

[aleclarson]

Very interesting! Only for numeric keys though, so it's an edge case we'll mention in documentation.

Sounds very fragile. I suggest to return Map instead of object.
