Lesson: Selecting from many options with Switch Statements

If you have many options to choose from, use a switch statement. A switch statement tests a value and can have many case statements which defines various possible values. Statements are executed from the first matched case value until a break is encountered.

Here is a pseudocode example:

switch (num) {
  case value1:
    statement1;
    break;
  case value2:
    statement2;
    break;
...
  case valueN:
    statementN;
    break;
}

case values are tested with strict equality (===). The break tells JavaScript to stop executing statements. If the break is omitted, the next statement will be executed.
