Javascript Dictionaries – Reducing and combining?

Currently working on a relatively simply project.

Let’s say I have a dictionary as follows:

{
Catco: 230,
DogsRUs: 100,
ChickenLickin_US: 100,
ChickenLickin_APAC: 200,
ChickenLicken_EMEA: 100,
Foxtrot_1: 23,
Foxtrot_34: 34
}

I’m looking to reduce and combine entries that are similar, but seperated by a very fine line. This dictionary is subject to change, but principly I’d like to productionize it so it can run fine and merge what needs to be merged.

    {
Catco: 230,
DogsRUs: 100,
ChickenLickin: 400,
Foxtrot: 57
}

I’ve looked into reduce and regex, but I figured I’d touch here for some starting notes. Thanks a lot!
