Enum in JavaScript

We are using enum in server side scripting language, recently I come across requirement where I have to write lots of if-else if clause, then I found the interesting thing which is enum.

Lets see how we can declare enum.

var Technology = 
{ 
    Microsoft: 0,
    PHP: 1,
    ROR: 2,
    Java: 3
}

Minor change in declaration, now lets see how we can use enum.

function Show(tech) {

    var msg = 'Welcome to the world of {0}';
    switch (Number(tech)) {
        case Technology.Microsoft:
            alert(String.format(msg, 'Microsoft'));
            break;
        case Technology.PHP:
            alert( String.format(msg, 'PHP') );
            break;
        case Technology.ROR:
            alert(String.format(msg, 'ROR') );
            break;
    }

}


//And here is the function call
Show(0);
Show(Technology.PHP);
Show(Technology.Microsoft);
Show(2);
