Learn the basics of Ruby with hands-on practice.

Become a Ruby Professional

Do you want to be an interpreted language geek? Are you tired of getting entangled in the dense syntaxes? Does it irritate you to compile your code to machine language first? Are you looking for an easy-to-use scripting language? Well, Ruby is the best pick for you then!
This introductory module will be providing you with hands-on practice with the support of a bunch of interactive illustrations, exercises, and the integral topics of variables, built-in classes, objects, conditionals, blocks, and much more!

## Methods of the `Hash` class
The main purpose of a `Hash` object is to look a value up by a key. However, there are a few more things we can do with hashes. Below is a list of methods supported by the `Hash` class. Don’t be too concerned with memorizing all of them.


### The merge method
We can merge two hashes by calling the `merge` method:
