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

Try using .call() to invoke the function. That way you can specify the context directly.

Like this:

this.countChildren.call(this, n, levelWid);th, level+1

Edit: Noticed my error, what you should really do is bind the anonymous function:

like this:

  n.children.forEach(function (n) {
    this.countChildren(n, levelWidth, level+1);
  }.bind(this));
