has-value
Returns true if a value exists, false if empty. Works with deeply nested values using object paths.
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.
flat
Take a nested Javascript object and flatten it, or unflatten an object with delimited keys
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).
postcss-nested
PostCSS plugin to unwrap nested rules like how Sass does it
