JIT COMPILER Meaning and
Definition
-
A JIT (Just-In-Time) compiler is a type of compiler that dynamically compiles code at runtime, instead of beforehand. It is designed to optimize the execution of programs by converting them into machine code or bytecode just before they are executed. This allows the compiler to take advantage of runtime information and make more efficient decisions on how to translate the source code.
A JIT compiler works by taking the source code of a program and converting it into an intermediate representation, such as bytecode or an abstract syntax tree. During runtime, as the program is executed, the JIT compiler compiles the intermediate representation into machine code specific to the underlying hardware. This allows the program to execute faster than if it were interpreted or compiled ahead of time.
The main advantage of using a JIT compiler is its ability to generate code that is optimized for the current execution environment and runtime context. This results in better performance compared to statically compiled code that may not take into account the dynamic nature of the program.
JIT compilers are commonly used in programming languages or frameworks that use bytecode, such as Java or .NET. They are responsible for translating bytecode into machine code and providing the necessary optimizations to improve the program's performance.

Etymology of JIT COMPILER
The term "jit compiler" is a short form of "just-in-time compiler". Here is the etymology of the term:
1. Just-in-time: The phrase "just-in-time" originated in the field of production and inventory management. It refers to a strategy in which materials or components are acquired and processed only when they are needed, avoiding unnecessary inventory buildup. This concept has been applied to various fields, including computer science.
2. Compiler: In computing, a compiler is a program that translates computer code written in one programming language into another language (usually a lower-level language) that can be understood and executed by a computer. The term "compiler" originates from the idea that it compiles or brings together different parts of a program into a single executable entity.
