Mojo is a new programming language that aims to provide high-performance capabilities while being easy to use and memory-safe. It draws inspiration from languages like Python, Rust, and Zig, and is designed to work seamlessly with Python. The language is still in its early stages, with a roadmap that outlines its planned development phases. Mojo's goal is to become a general-purpose language for high-performance CPU, GPU, and accelerator programming.
