JavaScript switch Statement

Conditional statements are used to perform different actions based on different conditions. Use the switch statement to select one of many blocks of code to be executed. The list below shows how the switch works: 
 switch( n ) {
   case 1:
     execute code block 1
     break    
   case 2:
     execute code block 2
     break
   default:
     code to be executed if n is
     different from case 1 and 2
 }

  1. A single expression n (most often a variable) is evaluated once.

  2. The value of the expression is then compared with the values for each case.

  3. If there is a match, the block of code associated with that case is executed.

  4. Use break to prevent the code from running into the next case.
