It's a web framework, similar to React/Angular/Vue. It comes with router and xhr utilities (like Angular), but it's smaller and faster than React/Vue.
What makes it interesting is that it has a very pragmatic philosophy: if you have 10 mins to spare, going over the getting started guide will cover the majority of what is really needed to build a meaningful web app, which makes it ideal for devs who aren't interested in complicated webpack setups and just want to get stuff done (you can use it idiomatically from a plain HTML and a CDN, even).
People like Mithril because it's more "vanilla JS" than other frameworks.
