JIT Compiler

A Just-In-Time (JIT) compiler is a system that improves a program’s performance by translating code into machine language as needed, during its execution. Instead of pre-translation, JIT compiles parts of the code on the fly, based on how the program runs. This allows for faster execution because the code is optimized for current conditions and only the necessary parts are compiled, reducing startup time and improving overall efficiency. Commonly used in environments like web browsers and virtual machines, JIT compilers help software run smoothly and quickly without requiring lengthy pre-processing.
