Just-In-Time Compilation (JIT)

Just-In-Time Compilation (JIT) is a technique used in programming languages to improve the execution speed of programs. Instead of translating all code into machine language (which the computer understands) before running it, JIT converts parts of the code to machine language at runtime—just as they are needed. This allows programs to run faster because the most frequently used code is optimized and stored for quick access. JIT compilation is commonly used in environments like Java and .NET, balancing the advantages of interpreted languages and compiled languages for better performance.
