1/* Notes:
2	1. written like synchronous code
3    2. compatible with try/catch blocks
4    3. avoids chaining .then statements
5    4. async functions always return a promise
6    5. function pauses on each await expression
7    6. A non promise value is converted to 
8       Promise.resolve(value) and then resolved
