a it's just a promise find any basic tutorial about javascript Promises
Use this syntax if you are in async function
const value = await a();
OR simply :
a().then(value => console.log(value)) ;

One trick is to write ‘(async function() { ... })();’ replacing the ... with all code you would normally write. That resolves the issues found with promise land and allows await to work how you expect it in other languages. – TamusJRoyce Aug 17 '19 at 02:14
