What is the best way to extract the address pieces from this google places API address result?

This may be a simple JSON related question. I'm successfully receiving a JSON object from Google Places API that looks exactly like this example from the Google Places API docs. I need to assign each of the address components (street number, city, state, zip, etc...) to a separate variable in my code. How do I, for example, best reference the street_number ?

Here's how I'm doing it now and it will not work, because, for example, if my address does not have a 'floor', then I would have to reference address_components[0] instead of address_components[1] . Here's the way that I'm doing it now that will not work:

const MyStreetNumber =  details.address_components[1].long_name
console.log(MyStreetNumber) //logs 48

And here is the definition of 'details' (the response i'm receiving from Google Places API) :
