Rust
Rust is a systems programming language focused on safety, speed, and concurrency. It provides memory safety without garbage collection through its ownership system, making it suitable for performance-critical applications like operating systems, game engines, and web servers. The language emphasizes zero-cost abstractions, ensuring high-level features don't incur runtime overhead.
Developers should learn Rust when building systems where performance, reliability, and security are paramount, such as embedded systems, blockchain platforms, or web assembly modules. It's ideal for projects requiring fine-grained control over memory and hardware, while preventing common bugs like null pointer dereferences and data races through compile-time checks.
