Unable to get started

HI, I am very excited to start using this but I am struggling to get this working at all.

i keep getting messages saying
const sleep = (duration: number) => new Promise(resolve => { setTimeout(resolve, duration) });
^
SyntaxError: Unexpected token ':'

and so on when simply running your example script with the latest versions

Are you using TypeScript?
