Ruby Methods

Ruby methods prevent us from writing the same code in a program again and again. It is a set of expression that returns a value.

Ruby methods are similar to the functions in other lnguages. They unite one or more repeatable statements into one single bundle.

Defining Method

To use a method, we need to first define it. Ruby method is defined with the def keyword followed by method name. At the end we need to use end keyword to denote that method has been defined.

Methods name should always start with a lowercase letter. Otherwise, it may be misunderstood as a constant.
