Understanding JIT Compilation in CPython

This chapter examines the collaboration between the Just-In-Time (JIT) compiler and the adaptive interpreter in CPython, focusing on their roles in optimizing code execution. It highlights key aspects such as dynamic type handling, the balance between JIT aggressiveness, and efficient memory management in different programming environments. The discussion also addresses the complexities and future possibilities of JIT compilation, including its application in resource-constrained contexts like MicroPython and compatibility with frameworks like WebAssembly.
