2. Use the term firebase over db
3. Functions to be modular, pass params and return the result than mutate global variable inside
4. () ? a : _ ternary operator could be replaced with if() a
5. Utils are mostly for functions that may not fit anywhere e.g. sorting algorithm, generating IDs. Should not be used for view methods
