Java JIT

Partially or fully converts a program into native machine code, so JVM interpretation is not needed and thus runs much faster.

Drawbacks

1. Compile needs more time
2. Result executable is larger which can cause paging when loaded into memory and may slow down the program

Alternative Approach - Lazy Evaluation

Not JIT compile the code until it’s necessary.
