This native code is then cached in memory, allowing subsequent executions of that block to bypass the interpreter entirely, resulting in significant speed improvements. JIT, conversely, focuses on runtime optimization.
Define JIT Compilation Runtime Process
Once a threshold is met, the JIT compiler activates, transforming that specific block of intermediate code into highly optimized native machine code. This means the generated code can utilize specific processor instructions that might not be available on older machines, ensuring optimal performance on modern hardware.
As the program executes, the system profiles the code to identify "hot paths," or sections that are executed frequently. JavaScript engines, such as Google's V8 used in Chrome, rely heavily on JIT to deliver the high performance required for complex web applications.

Security researchers also analyze JIT code generation as an attack surface, since runtime compilation can potentially be manipulated. NET Common Language Runtime (CLR).
