Braking javascript Promises are such a mess

Just one of many examples of recently silently braking code:

balance=web3.eth.getBalance(sender); console.log(balance.toFixed(3))

Used to work, now it prints NaN. What's going on? Well getBalance now returns a Promise. IMHO thats the worst category of bug introduction the industry has seen after the goto keyword.

It can't even be fixed by simply adding the await keyword, it has to be wrapped in an async function.

balance=await web3.eth.getBalance(sender);

Top level await is not allowed in node.js.
