Just to remind you that we did have server-side JavaScript 25 years ago ... Nothing new really ... just well-forgotten old.

🤦 Remember that quote from Brian Kernighan:
"Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it."

Let’s be real, friends — most days we just… write code (or stare at it until it fixes itself) 🙂
P.S.
And yes, of course I generated the version on the right with my personal AI assistant. It knows me a little too well, doesn’t it? 😄

Admit it - you like #JavaScript! It’s fine, this is a safe space ... confess the truth. You write JavaScript.

JavaScript has its 30th birthday today! 🎂 I'm attaching a function that calculate its age 😂.
In its lifetime it has given us:
- Pop-up ads 👀
- jQuery magic ✨
- Callbacks 😵
- Promises 🙂
- async/await 😍
- ... and React hydration errors 🤬
What a journey. Happy 30th Birthday, you chaotic legend!
