PyPy and Numba are both tools that leverage JIT (Just-In-Time) compilation to enhance performance, but they serve different purposes and have distinct implementation approaches. Here's a breakdown:
📌 Key Differences
PyPy
- A Python interpreter written in Rust, focusing on speed and compatibility with CPython.
- Uses Tracing JIT to optimize code at runtime.
- Example: PyPy's official website
Numba
- A Python compiler for numerical computing, built on LLVM.
- Specializes in CPU-bound tasks like math operations and array processing.
- Example: Numba's GitHub repository
🧠 Use Cases
| Tool | Ideal For |
|---|---|
| PyPy | General Python applications, speed-critical code |
| Numba | Scientific computing, data analysis |
