Answer is JIT

JIT compiler provides the transaltion of a bytecode of one system to the other system. It combines speed of compiled code with interpretation, overhead of an interpreter and the additional overhead of compiling. JIT is also known as Just In Time Compiler which is a form of dynamic compilation and allow the dynamic recompilation. It is used in the dynamic programming environment as it is a runtime system that can handle late-bound data types and enforce security guarantees. The overall function of it goes like this:

1. Source code is translated to an intermediate representation called as bytecode.

2. Bytecode is not the machine code but it is an intermediate code which is portable among computer architectures.
