Recursively iterates over collections arrays and objects

Iterate over the enumerable properties of an object, and return an object with properties that evaluate to true from the callback. Exit early by returning `false`.

Faster, node.js focused alternative to JavaScript's native array map.

Convert an argument into a valid iterator. Based on the `.makeIterator()` implementation in mout https://github.com/mout/mout.

Similar to map for arrays, this creates a new object by calling the callback on each property of the original object.

`Array#forEach()` but it’s possible to define where to move to next

Standard library iterator utilities.

Iterate any JS iterator. Works robustly in all environments, all versions.

Create an iterator which computes the base `b` logarithm.

Create an iterator which invokes a function for each iterated value before returning the iterated value.

Test whether at least one element in a collection passes a test implemented by a predicate function, iterating from right to left.

Iterate any iterable JS value. Works robustly in all environments, all versions.

Create an iterator which evaluates the Bessel function of the first kind of order one for each iterated value.

Perform a single-pass map-reduce operation against each element in an array and return the accumulated result.

Test whether all iterated values are truthy.

Create an iterator which both filters and maps the values of another iterator.

Create an iterator which rounds each iterated value to the nearest power of two toward zero.

Evaluate the terms of a continued fraction.

Create an iterator which skips the last value of a provided iterator.
