Switch Statement

Instead of writing many if..else statements, you can use the switch statement.

The switch statement selects one of many code blocks to be executed:

switch (expression) {
  case x:
    // code block
    break;
  case y:
    // code block
    break;
  default:
    // code block
}

This is how it works :

• The switch expression is evaluated once
• The value of the expression is compared with the values of each case
• If there is a match, the associated block of code is executed
• The break statement breaks out of the switch block and stops the execution
• The default statement is optional, and specifies some code to run if there is no case match
