Using the switch Structure
JavaScript offers the switch statement as an alternative to using the if...else structure.
The switch statement is useful when testing all the possible results of an expression.
The format of a switch structure looks like the following:
<source lang="javascript">
switch (expression)
{
case label1:
statement1;
break;
case label2:
statement2;
break;
default:
statement3;
}</source>
