Ruby Variables
myVar = 48 In Ruby, a variable is a place to store values of almost any type including Integer, Boolean, String, Array, and Hashes.
Each variable has its own name which cannot begin with a capital letter or a number and we use the equal sign for assigning a value to that variable.
The variable declaration does not require that you mention a specific data type.
The following program declares myvar variable and assigns the value 48.
