Disallow for-of

The style guide 11.1 says that you shouldn’t use for-of and instead should use forEach (which I completely agree with).

That said, the ESLint rule no-iterator doesn’t seem to enforce this, and the entry for no-restricted-syntax contains ForInStatement but not ForOfStatement.

Can we add ForOfStatement to no-restricted-syntax (or is the a better way of restricting for-of statements?

@dplusic in nice, simple ES6:

function foo(args) {
  return args.reduce((prev, arg) => prev.then(() => bar(arg), Promise.resolve());
}

@dplusic @ljharb I don’t understand. Where’s the advantage in making your code totally unreadable? Purity is nice, but not when it takes 30 minutes to decipher a simple function.
