The switch Keyword

What is the switch Keyword?

The switch keyword allows us to specify the different actions the program can perform based on the value of a particular expression.

In an if-else expression, the condition always returns a boolean. This means that it can only cater for two cases: true and false.

With a switch keyword, the conditional expression is not restricted to booleans. Hence, we can define the behavior of the program for several cases. These cases are separated by the pipe operator, |.
