This is really an overly simplistic way to code. I urge people to think deeper up front about performance.
Know your performance goals going in and code accordingly. If you require 100 micro average latency and you coded in Node.js, step 3 will be a rewrite.
Every single line of code I write, I can tell you my performance goals. If indeed it is a simple crud screen by a user, the goal may be "meh, document.ready called when viewed from 100ms browser lag within 1 second". Backend trading code would have different goals..
