javascript switch(true)

Question

Hi i am trying to handle an ajax json response

here is my code

success: function (j) {     
    switch(true)
    {
        case (j.choice1):

            alert("choice2");
        break;
        case (j.choice2):
                alert("choice2");
        break;
        default:
            alert("default");
        break;
    }
}

based on what j is return i do my action BUT i keep getting the default.

I have alert the j values and come correct.Some how case (j.choice1) case (j.choice2) is not working.

I tried case (j.choice1!="") (j.choice2!="") But in this scenario i keep getting the first choice.

What am i missing

It works for me:

var a = 0, b = true;
    
switch(true) {
    case a:
        console.log('a');
        break;
    case b:
        console.log('b');
        break;
}
