That’s a great start for people wanting to learn to access Firebase. But I think people are going to run into immediate challenges when trying to access more complex data structures.

Three things I’d like to see added to this video or expanded upon in a follow-up video:

  1. How to use the Join command to specify a path to a Firebase key, especially when variables such as userId are involved.

  2. How to access an item in an array (aka list) and loop through an array from Firebase.

  3. How to specify object properties using a single text string such as “Property.subProperty[1].leafProperty”

Also, an explanation or link to how to parse JSON (e.g. using CodeBeautify) would be useful since it can be confusing for people to figure out how to reference certain property key names.
