iters

Provides functions for simplifying the usage of iterables.

Functions

iters.each(object: iterable, callback: function): Calls function callback for each item in the iterale object and pass the item and index as arguments to the callback function. The callback function should capture the item its first parameter and if the index of the item in the iterable is needed, it can be captured in the second item.

iters.reduce(list: list, callback: function [, initial: any]): Executes a user-supplied “reducer” callback function on each element of the list, in order, passing in the return value from the calculation on the preceding element. The final result of running the reducer across all elements of the list is a single value.
The first time that the callback is run there is no “return value of the previous calculation”. If supplied, an initial value may be used in its place. Otherwise the list element at index 0 is used as the initial value and iteration starts from the next element (index 1 instead of index 0).

iters.map(list: list, callback: function): Creates a new list populated with the results of calling the provided callback on every element in the list.

iters.some(list: list, callback: function): Tests whether at least one element in the list passes the test implemented by the provided function. It returns true if, in the list, it finds an element for which the provided function returns true; otherwise it returns false.

iters.every(list: list, callback: function): Tests whether all elements in the list passes the test implemented by the provided function. It returns false if, in the list, it finds an element for which the provided function returns false.

iters.filter(list: list, callback: function): Creates a new list with all elements that pass the test implemented by the provided function.
