Can I check for not equal in a JavaScript switch statement?

Question

var t = "TEST";
switch(t){
    case !"TEST": /* <- does not work. Can you check if t does NOT contain a string? */
        alert("t != TEST");
    break;
}

Can you do this with a switch statement?

Answer 1

you can also do this:

var str = "TEST";

switch (true) {
    case (str !== "TEST") :
        alert("str !== TEST");
        break;
    case (str === null) :
        alert("str is null");
        break;
    default:
        alert("default trigger");
}

Answer 2

You can use if. If you prefer switch, use a 'default' case and an if condition there like

default:
    if(n == -1){
        //Your code
    }
    break;
