Rust is the only language with the same low-level memory model of C/C++ (no garbage collector, focus on zero cost abstractions, etc) while also being memory-safe (like nearly all popular modern languages besides C/C++). Before Rust, you often had to choose between memory safety and performance.

This looks like how React components are written if you make the weird choice of not using the JSX syntax extension for React elements. I wonder if you could make a JSX-like DSL with Rust macros. JSX really helps for making this kind of stuff bearable.
