But the borders between frontend, backend, and design are blurring, and AI is holding the eraser. In this talk, we'll confront the identity crisis head-on and explore the mindset shifts needed when frontend stops being a role and starts being a skill. **19:10 - Sagi Carmel** -Founder and CTO @ Reeeally **Why I choose AstroJS instead of NextJS in 2026?** In the landscape of the JS ecosystem this one framework isn't the most know, and just like other great things it should!

Let's explore why by using nextJS as comparison. **When?\*** Wednesday, 13 May 2026 - **18:00 We start on time!** \* = (לאור המצב.

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.
