Question

Is there a way to choose dynamicaly an operator

do something like this:

     var ​val1="1",
         val2="1",
         oper="===";
     if(val1 oper val2){
         console.log("im in"); 
     }else{
         console.log("im out");       
     }

You can not do a dynamic operator, but you can achieve the same thing using functions instead.

var ​val1 = "1",
    val2 = "1",
    oper = function(a, b) { return a === b; };

 if(oper(val1, val2)) {
     console.log("im in"); 
 } else {
     console.log("im out");       
 }
