> Seems like it's obsolete. Then you can write your own Deferred implementation. I didn't even know it was implemented in browsers. const run = async () => { ... } How to read this? run is a constant that equals the result of calling function async() thas maps to something in curly brackets? This is confusing. > If you want to write async code, use async / await. That is a good idea, but it has nothing to do with arrow functions. > It also allows you to do scope binding in a different manor `this` binding in JS in classic functions is broken by design, so yes, that is the advantage of arrow functions.
