array-sort
Fast and powerful array sorting. Sort an array of objects by one or more properties. Any number of nested properties or custom comparison functions may be used.
union-value
Set an array of unique values as the property of an object. Supports setting deeply nested properties using using object-paths/dot notation.
deeks
Retrieve all keys and nested keys from objects and arrays of objects.
nested-property
Read, write or test a data structure's nested property via a string like 'my.nested.property'. It works through arrays and objects.'
get-value
Use property paths like 'a.b.c' to get a nested value from an object. Even works when keys have dots in them (no other dot-prop library we tested does this, or does it correctly).
