What are the advantages of Just-In-Time compilation?

Just-In-Time (JIT) compilation offers several advantages, including improved performance, as it compiles code at runtime, optimizing it for the specific hardware. It also allows for dynamic optimizations and can reduce memory usage by compiling only the necessary parts of the code.

Can you explain how JIT compilation improves performance?

Certainly! JIT compilation improves performance by translating bytecode into native machine code just before execution. This allows the program to run faster since the CPU can execute native code directly, and it can optimize the code based on the current execution context.

Are there any downsides to using JIT compilation?

Yes, there are some downsides. JIT compilation can introduce a startup delay since the code needs to be compiled at runtime. Additionally, it may consume more memory due to the need to store the compiled code and can lead to increased CPU usage during the compilation process.

How does JIT compare to Ahead-Of-Time (AOT) compilation?

JIT compilation occurs at runtime, allowing for optimizations based on current conditions, while AOT compilation translates code before execution, which can lead to faster startup times but may miss runtime optimizations.
