I think one of my favorite aspects of programming is the intentional style you implement as you get better at what you do. This isn’t limited to JavaScript, but it leaves the door open for each project to present a new way of doing something a little bit better. All of those ‘little bits’ add up and that’s why we want to crawl in a cave when we look at code we’ve written a year ago. I don’t see it as a bad thing, instead I look at it as validation that we’re progressing, that we’re getting better. That’s very important in preventing burnout and staying inspired to do what we do every day.
