Number one this week, Solid is a library to build UI similar to React.

Components are written using JSX but it does not rely on the Virtual DOM like React does.

The reactivity is handled in a different way, using one of the “reactive primitive” the API provides, createState being the most basic one. Under the hood, it uses proxies to track when a value change.

It’s not only the fastest UI framework according to the benchmarks but it’s also the one with the smallest bundle size, check the implementation of the famous Real World example app to get a better understanding of Solid.
