JIT compiler

A just-in-time (JIT) compiler is a part of the runtime environment for Python that compiles bytecode into machine code at runtime. This approach contrasts with traditional ahead-of-time (AOT) compilation, which compiles the entire program before execution.

By compiling code just in time, a JIT compiler can optimize the execution of your program based on the actual runtime context, potentially improving performance significantly.
