czycha / count-map Goto Github PK

Hi! While implementing my own filter extensions, I discovered that it would be nice to have a method to clone just the config, without entries. That way I could copy the ones I'd like to keep, rather than copying all and then deleting the ones I don't need.

Hi! Thanks for your project, it is very useful!
Could you maybe add a .rangeFilter(min, max) method that returns a new CountMap with only values that are in range? If one or both limits are null or undefined, their check should be ignored. Thus, .rangeFilter(null, null) would effectively clone the map.

Edit: Even nicer would be if I could give multiple acceptable ranges in one call, saving the concat. This could be done by providing an array as the first argument like .rangeFilter(ranges) where ranges = [ [1, 2], [8, null] ] which would give all entries with value 1, 2, 8 or more than 8.
