JIT stands for Just In Time.

In software world, this term refers to 'just in time compilation'.

It's the translation of computer program into machine language during execution time.

This translation is usually done by a virtual machine (VM).

As the term implies, this translation is only done to a certain part of the program which is needed for execution at a given time.

Some languages support compiling of the human readable syntax to an intermediate form. For example, a Java compiler compiles java code to bytecode. HotSpot JVM converts the bytecode into machine language which a computer can understand.

JIT compiler is part of a VM.
