Did you know about ES6/ES7 and babel? It allows you to write code like this:
const readFile = promisify(require('fs').readFile);
async function f(filename) {
const content = await readFile(filename);
return content.trim().length;
}
I'm not sure another async syntax on top of JavaScript will have a chance
of gaining traction at this point, unless there are very compelling reasons.
* The async/await ECMAScript
proposal: https://github.com/tc39/ecmascript-asyncawait/
* babel: https://babeljs.io/
Your project can still be a lot of fun, just mentioning this as a potential
alternative. :)
Cheers,
Jan
