What are the differences between JIT, AOT, and static compilation?

What are the differences between JIT, AOT, and static compilation?

JIT (Just-In-Time) compilation compiles code at runtime, AOT (Ahead-Of-Time) compiles it before execution, while static compilation is done at build time.

Can you explain the advantages of using JIT over AOT?

JIT can optimize code based on actual runtime data, potentially leading to better performance, while AOT can reduce startup time.

Are there any scenarios where static compilation is preferred?

Yes, static compilation is preferred in environments where performance and predictability are critical, such as embedded systems.

How do these compilation methods affect memory usage?

JIT may use more memory due to runtime compilation, AOT can have a larger binary size, while static compilation typically has a fixed memory footprint.

Which method is best for web applications?

It depends on the use case; JIT is often used in dynamic web applications for flexibility, while AOT can be beneficial for performance in static sites.
