`keys()` returns an array of: **a)** Nestedly occurring `keys` or `indexes` (eg `Set` keys, array indexes etc) or **b)** `props` of the input value (props on all objects), including symbols, own & inherited, enumerable & nonEnumerable! The returned props can be filtered by prop type (string or symbol), enumerability, own/inherited, top-level props etc.

A Simplified typings version of `keys()` that returns only `string` or `symbol` props types of the input value, based on the options.

each
Iterate over the (many) items of a value, calling the callback for each item. Think of `_.each()` or `Array.forEach()`, but more powerful via [ `z.loop()` ](../functions/loop.html ). Hence, it works with ANY value, not just arrays and objects, but also `Map`, `Set`, `Iterator`, `Generator` & even `AsyncIterators` (where it returns a promise resolving when iteration ends!

take
Takes `n` elements from the beginning of the value ( `Array`, `Object`, `Set`, `Map` etc). If `n` is a function, it stops as soon as it returns `false` or `z.STOP`.
map
Map over the (many) items of **any possible input value**, returning a new instance of the same input value type (if possible), with the results of calling the projector/mapping function on every "nested" element of the input value (for collections like Objects, Arrays, Maps, Sets but also for Iterators, Generators, AsyncIterators etc).

filter
Filter over the (many) items of a value and returning of **a new instance of the value**, containing the elements that pass the filter with [ `isPass` ](../functions/isPass.html ) (an elaborate kind of truthy). Value can be `Object`, `Array`, `Map`, `Iterators` and many more.
