Modularize Your Code
Entangled in the habit of writing uncomfortably long pieces of code? Organize your code into smaller pieces that improve readability for your, and anyone else’s, later reference. It may be a difficult habit to get into, but the rewards will show up later on.
If you modularize your code, you will find it relatively easy to make the most of Node’s asynchronous philosophy. Keeping chunks of code small will help you during the development of complex applications in Node.js.
