javascript return of recursive function

Question

Hate to open a new question for an extension to the previous one:

function ctest() {
    this.iteration = 0;
    this.func1 = function() {
        var result         


        

Answer 1

You have to return all the way up the stack:

func2.call(this, sWord);

should be:

return func2.call(this, sWord);
