Python 3.14 and its New JIT Compiler

Python 3.14 introduces an experimental Just-In-Time (JIT) compiler aimed at improving the language's execution speed for CPU-bound tasks. The JIT works by monitoring frequently executed code paths and translating their bytecode into native machine code, which runs much faster on subsequent calls. While still an opt-in feature activated by an environment variable, it is now bundled with official installers, signaling it is ready for broader testing. The content provides a technical overview and a comprehensive benchmarking suite, including code for Mandelbrot, Dijkstra, and Levenshtein distance workloads, to measure the performance gains.
