make-sort-key 
Combine several strings to make one sort key.
The following transformations occur:
- inputs are lowercased,
- accents are removed,
- redundant spaces are removed,
- null, undefined or empty inputs are ignored,
- finally, resulting strings are concatenated with a space separator.
Installation
npm install --save make-sort-key
