/*
  
  so uhm, up until about a week ago, my 
  defacto method for handling errors in an 
  async/await program-flow was to wrap my 
  entire code-block in a try/catch; performing 
  the operations in the `try {}` block and 
  handling any errors in the `catch(err) {}` block.
  
  it worked well, but it didn't sit well with me
