Just In time Compiler
In computing, just-in-time (JIT) compilation (also dynamic translation or run-time compilations) is a way of executing computer code that involves compilation during execution of a program (at run time) rather than before execution. This may consist of source code translation but is more commonly bytecode translation to machine code, which is then executed directly. A system implementing a JIT compiler typically continuously analyses the code being executed and identifies parts of the code where the speedup gained from compilation or recompilation would outweigh the overhead of compiling that code.

Interpreters and Compilers
An interpreter is that directly executes instructions are written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program.
A Compiler is that translates computer code written in one programming language (the source language) into another language (the target language).
Example of Compilers
- Take one language and convert into a different one.
