Why do we need "initialization" in this particular app?

Why wasn't initialization required in "Fun Facts" app? What other scenarios (and app examples) are there where we might need it?

In Fun Facts, there was initialisation but only internally and implicitly by the use of the let statement. Here, we are getting the data from an external source, hence the need to initialise. Supposing we get facts from an external service which return facts in JSON, we will be initialising the facts data.
