 The switch statement can sometimes be a useful alternative to a concatenation of if statements. This is the case when the condition is an expression that can be decomposed into a number of distinct values or cases, as shown in the example below.
+Depending on the value of the expression specified in the `switch` clause, one of the `case` statement blocks is executed. Each statement block should end with a `break` statement to ensure that a `case` doesn't 'fall through' into the next `case`.
+
+The `default` statement at the end is executed when none of the preceding cases hold true. The `default` statement is not strictly required, but is a best practice to always specify one.
