Codetown ::: a software developer's community
Ivar came to the Swamp for the #j4kio conference a few days ago. He had just been in South Africa giving a presentation. And, just before that, we met up in Crete for the fabulous www.jcrete.org conference. #jcrete How about that! Ivar lives in Sweden. He keeps fit and always rents a car wherever he goes so he can explore the area. In just a few days, if you missed the www.j4k.io conference, there will be similar talks, including Ivar, on a virtual Jakarta webcast. That's Aug 10th. I'll put the details up on www.Codetown.com. Ivar, great seeing you!

ArrowJS, developed by Justin Schroeder, is a reactive UI library that has reached its 1.0 release after three years in development. It utilizes core web technologies, avoids JSX and compilers. Notable features include an optional WASM sandbox for executing untrusted code. The framework's minimalism is highlighted by its reliance on three main functions: reactive, html, and component.
