I didn't do anything to prevent the unnecessary re-rendering of a React component that used the Google Location API. Within a few hours of it going live, we hit our max amount of free API calls and the whole feature was basically useless for 24 hours 🙃

Thankfully this was when we were slowly reskinning / revamping our product, so clients could still use the old version and knew there wouldn't be a seamless transition until everything was finished.

And that's how I learned why performance lifecycle functions are important.
