New testimonial just in!

🚀 ONLY 2 DAYS TO GO! Developers, we really hope you're buzzing with excitement, because we know we definitely are... 🫠 The countdown is almost over, and we absolutely can’t wait to open the gates to Višnjik Sports Hall! See you all soon at #ShiftZadar 2025! 💚…
🇭🇷 An early start to get to @InfobipShift! See you there?

I love @ChromeDevTools’s Snippets, but they don’t take parameters which means you need to change the snippet itself every time. One way around it is to take input from `prompt()`!
