Why is the value overwritten by the last iteration in a recursive traversal?

Question

JavaScript

Here is an example https://jsfiddle.net/x4gyg9qp/ ideally you want the first value displayed in the console.
I expected that on the contrary, by the end of the line will be filled with all the titles.

Answer 1

Because when you recursively call, nothing is returned back.
