I'm working with some JSON objects about homes. The JSON looks like the below. How would I use Javascript parsing to pull out the "yearBuilt" value? It's part of the building array, which is part of the parcel array.

I've explored looping based on other similar asked-questions, but can't arrive at anything that seems to work. Thanks!
