    The JavaScript switch statement is used to execute one code from multiple expressions. It is just like else if statement. But it is convenient than if..else..if because it can be used with numbers, characters etc.

    Syntax:

    1. switch(expression){ 
    2.  
    3. case value1: 
    4.  
    5.  code to be executed; 
    6.  
    7.  break; 
    8.  
    9. case value2: 
    10.  
    11.  code to be executed; 
    12.  
    13.  break; 
    14.  
    15. ...... 
    16. default:
    17.  code to be executed if above values are not matched;
    18. }
    Example 
    1. <!DOCTYPE html>
    2. <html>
    3. <body>
    4. <script>  
    5. var grade='B';  
    6. var result;  
    7. switch(grade){  
    8. case 'A':  
    9. result="A Grade";  
    10. break;  
    11. case 'B':  
    12. result="B Grade";  
    13. break;  
    14. case 'C':  
    15. result="C Grade";  
    16. break;  
    17. default:  
    18. result="No Grade";  
    19. }
