On another thought, I've been travelling for conference talks.
I gave a talk at many conferences this year and absolutely loved it 💖.
I have been to Reactathon in SF, California, App.js in Krakow, Poland and ChainReact in Portland, Oregon. I had a great time meeting amazing folks in the community, and I always left with a lot of energy.
Next week, I have a couple of Youtube videos dropping, subscribe to my channel if you haven't already.
Our Weekly Snack: React's Re-rendering Patterns
We are building an app for setting the dark mode with a dogecoin as the logo. You can see that the Toggle button handler is the one that toggles the dark mode. We also have a Footer with our company logo on it.
Here is a quick snippet.
Every time the Parent container i.e. App renders, Logo, Footer and Toggle Button re-renders. We want to only re-render when necessary. This process of caching and only purging cache when necessary is called Memoization.
In our case, we want to memoize the logo as we prefer to keep the logo from re-rendering. We want to cache the logo. This is how we can memoize it.
We also want to memoize the dark Mode handler as we only wish for the dark mode to change when we toggle it, not just when the parent re-renders.
This will only make it so that handleToggle will re-render when dark mode changes; otherwise, React's natural behaviour is to re-render whenever the parent renders. And we want to avoid it at all costs.

There are still bugs being discovered, and I've started upgrading my course to Next.js.
I still foresee that the above will take much longer to stabilize and will be brief, although it is exciting.
