Comment by Davor Minchorov on "To anyone who's tried to learn (successfully or not) Node.js: What were your hurdles? What were your successes?"

I've taken a few Pluralsight courses on NodeJS and wrote a few scripts / a server which it wasn't too hard but the whole async nature of things and following / controlling the flow is the only problem I am still trying to figure out in detail.

I am talking about scenarios where you have to loop over an array of few items and run a method for each item but the function does an asynchronous call (redis) behind the scenes and after that is done, continue. Sometimes it feels chaotic a little bit.

Usually, these scenarios are not shown in tutorials, so I have to learn them by myself or ask for help.

Have you ever tried to use ES6 Promises? They will get things straight for you! You can makem an array, loop over async things and add the promises to the array. Then you just use Promise.all() to wait for all promises to finish (if you need to).

Yeah, I am currently researching that using promises with a library like Bluebird which has a lot more useful methods.

@maruru can u give us some example code on jsfiddle or codepen..

@ruffles Did you mean something like async.series or async.parallel?

@gbhasha here you go: jsFiddle
