Objects

Objects: picking, omitting, mapping values, emptiness and equality.

Export	What it does
deepMerge	Applies a partial patch to nested settings, such as saved preferences over the defaults: plain objects are merged at every depth, other values replace, undefined keeps.
isDeepEqual	Checks whether two values are equal at every depth: primitives (NaN equals NaN), arrays, objects with the same prototype, Date, RegExp, Map, Set and typed arrays.
isEmpty	Checks whether a container holds nothing: an empty string, array, Map, Set or object.
isShallowEqual	Checks whether two values are equal at the first level, with Object.is: skips an update when a new object carries the same values as the previous one.
mapValues	Transforms every value of an object, keeping its keys.
omit	Copies an object without some of its properties, without delete, which slows down V8.
pick	Copies some properties of an object into a new one.
