What are the differences between AOT and JIT compilation?

What are the differences between AOT and JIT compilation?

AOT stands for Ahead-Of-Time compilation, while JIT means Just-In-Time compilation. AOT compiles code before execution, resulting in faster startup times, while JIT compiles code during execution, optimizing performance based on runtime conditions.

What are the advantages of using AOT over JIT?

AOT offers faster startup times, reduced memory usage, and improved performance consistency since the code is pre-compiled. It's particularly beneficial for applications where startup speed is critical.

Are there any downsides to using AOT?

Yes, AOT can lead to longer build times and less flexibility during execution since optimizations are fixed at compile time. It may also result in larger binary sizes.

In what scenarios would JIT be preferred?

JIT is preferred in scenarios where runtime optimizations are crucial, such as applications with dynamic code execution or those that benefit from profiling information to optimize performance.
