I have used Node.js in production for about 5 years now and I must agree with the sentiment that JavaScript is "Easy to learn, impossible to master". Yes, error handling is a little confusing at first but it stems from JavaScript's asynchronous nature which is naturally complex for the linear mind. My personal sentiment is to just use Promises, like everywhere. ES7 async/await will really help with this too.
