Question

It is possible to do this using “dot syntax” without using “eval” (evil)? (I know I can do with this[methodtocall]())

    var myObj = {

      method1 : function(){
         return 1;
      },
      method2 : function(){
         return 1;
      },
      callMethod : function(methodtocall){
           this.+methodtocall+()
      },
      init : function(){
          this.callMethod("method1");
      }
   }
   myObj.init();

No, aside from eval or an equivalent, it’s not possible with the dot notation member operator.

If you want to maintain consistent syntax, then always use the square bracket notation of the member operator.

  callMethod : function(methodtocall){
       this[methodtocall]()
  },
  init : function(){
      this["callMethod"]("method1");
  }
