Like the array these elements are placeholders that are used to pass each key value pair into the code block as ruby loops through the hash.

Ruby each do with index.

The each iterator returns all the elements of an array or a hash. If no block is given an enumerator is returned instead. Let s look at these in detail. But in this article we re going to look at the each method how to use it and what you can do with it.

The ruby each loop. Calls block with two arguments the item and its index for each item in enum. Syntax collection each do variable code end. A negative index is assumed relative to the end of the array that is an index of 1 indicates the last element of the array 2 is the next to last element in the array and so on.

Ruby arrays can hold objects such as string integer fixnum hash symbol even other array objects. Given arguments are passed through to each. It s the ruby way of doing repeat until done. Iterators return all the elements of a collection one after the other.

The ruby method each allows you to go over a list of items without having to keep track of the number of iterations or having to increase some kind of counter. When it comes to doing the same thing over and over again ruby has a few methods you can choose from. Ruby arrays are not as rigid as arrays in other languages. For a hash you create two elements one for the hash key and one for the value.

This works exactly like the each method for an array object with one crucial difference. Before you can use each you need a collection of items like an array a range or a hash. We will be discussing two iterators here each and collect.
