I have a variable that can either be boolean false, or an integer (including 0). I want to put it in a switch statement like:

switch(my_var){

    case 0:

         // Do something

         break;

    case 1:

         // Do something else

         break;

    case false:

         // Some other code

}

In my tests in Google Chrome, it seems to work perfectly, but I'm a little nervous to use it because I'm afraid that in some browsers, if my_var is false, it might execute the first case since 0 == false.

I'm just wondering if there is anything official in JavaScript that says the switch statement will use strict comparison such that 0 !== false, but I can't find anything myself, and I'm not sure if this will work well in different JavaScript engines. Does anybody know if the comparison done by a switch statement is guaranteed to be strict?
