RUBY: Case expression

There are two forms of Ruby case expressions:

The first form is similar to a set of continuous if statements: it allows you to list a set of conditions and execute the first statement corresponding to the true condition expression.

In the second form, specify a target at the top of the case statement, and each when clause lists one or more comparison conditions.

 

• Like if, case returns the value of the last expression to be executed. If the expression and condition are in the same row, the then keyword can be used to differentiate them.
