Frequently asked questions
What is the difference between JIT and AOT compilation?
AOT (ahead-of-time) compilation turns source code into machine code before the program runs, giving fast startup and predictable performance. JIT compiles during execution, which costs startup time but lets the compiler optimise based on what the program actually does.
What does JIT mean in manufacturing?
It means parts and materials are ordered to arrive exactly when the production line needs them, so almost nothing sits in storage. It cuts holding costs but makes the operation vulnerable to supply disruption.
Is JIT the same in software and business?
The underlying idea is the same — do the work at the last responsible moment — but the fields are unrelated in practice. Context makes it clear which is meant.
