It is pretty neat. They've made a lot of really interesting design decisions that make for a pretty unique language.

One of its main selling points is how it guarantees memory safety without using a garbage collector. That, plus the fact that it does a shit-ton of compile-time optimizations, actually makes it pretty fast. Like, 80%-90% as fast as C (which is much faster than all the other high-level languages like Java, Go, etc, partly because they do in fact use garbage collectors).

If you want to check it out, I recommend this playlist as a solid intro.
