ofl
Convertion between nested object and flat one with delimited keys. Yet another flatten/unflatten module with few differences:
- no undefined values allowed
- only primitives in arrays (no nested arrays and so on)
- only plain objects
- empty objects are ignored when flatten
- only own and enumerable fields counts when flatten
- no key conflicts allowed in flat object
- no delimiter string in any key in nested object
It is intended to be useful for work with well-serializable config data.

patch, //cange some fields in flat object
validKeys, //test if array of keys are valid for flat object
validValues, //test if array of values are valid for flat object
} = require('ofl');
flatObj = flatten(nestedObj, delimiter);
nestedObj = unflatten(flatObj, delimiter);
//throw error if inappropriate object sent
//delimiter is optional, defaults to '.'
patchedFlatObj = patch(flatObj, diffFlatObj);
//throw error if diffFlatObj keys is not subset of flatObj keys
validKeys(Object.keys(flatObj));
validValues(Object.values(flatObj));
//throw error if inappropriate key or valueLicense
