"Hey Mike, check out my new function: getGlobalStatus"
"What does it do?"
"Oh, it sets Claim messages."
"What does it return?"
"Nothing."
"Do you see any issues with that name?"
"No."
I'm tired boss.

Why use React's conditional rendering to remove a tag when you could instead use a CSS module to always set the height to 1px and then import a different CSS module to conditionally set the height to "auto?" Shitty results, with 4 times the effort! Bonus: it's impossible to test and not accessible!

You need to enable JavaScript to use the Lean Game Server, as it is built using React.

Fun JS fact that might pop up: `formElement.submit()` will bypass your onSubmit handler and directly submit the form. But `.requestSubmit()` will trigger it like you'd expect! Here's an example with React, but it's a Form API, so it'll work anywhere.

Dang I'm excited about new semantic attr() capabilities in CSS!
I wrote a post about why this feature is so powerful, how it could change the way you build components, and how I would use it.
Advanced attr() is rolling out in Chrome 133 starting next week 🥰
