Ask HN: What is your favorite technology to build sideprojects or sidehustles?

I'm currently contemplating starting a sideproject, but with limited experience as a dev who actually deploys something, I'm really interested in some insights from others. I would be really interested in what technologies you (would) favor if you're building a sideproject, sidehustle or in any situation as a solo dev? In which context are you usually building apps and can you explain your choice (for example long experience, particular love for a specific framework, etc) I appreciate your insights!
