Javascript recursion within a class

Question

I am trying to get a recursion method to work in a class context. Within my class I have the following method:

    countChildren(n, levelWidth, level) {
            


        

Answer 1

the variable this Gets redefined within:

1. the inner scope of a for loop
2. within a inline function declariation
3. within asynchronous function calls.

I agree with krillgar with the declaration of self. it fixed my problem with an asynchronous call.

obj.prototype.foo = function (string){
   var self = this;
   if(string){ do something }
   else
   setTimeout(function(){
     self.foo("string");
     }, 5000);
}
