AOTkompilering

AOTkompilering, which stands for Ahead-Of-Time compilation, is a software development technique where code is compiled into machine code before the program is run. This is in contrast to Just-In-Time (JIT) compilation, where compilation occurs during program execution. The primary advantage of AOT compilation is improved performance. By compiling the code in advance, the overhead of runtime compilation is eliminated, leading to faster startup times and more consistent execution speeds.

AOT compilation typically happens during the build process of an application. The source code, or an intermediate representation of it, is translated into native machine code specific to the target architecture and operating system. This results in an executable file that can be run directly by the hardware without the need for a runtime compiler. This can also lead to smaller deployment sizes as the compiler itself does not need to be distributed with the application.

However, AOT compilation can have some drawbacks. It generally requires a compilation step for each target platform, which can increase build times and complexity. Also, if the compiled code is not optimized well for the specific runtime environment, it might not always outperform JIT compiled code which can adapt to runtime conditions. Despite these considerations, AOT compilation is widely used in scenarios where performance and predictable execution are critical, such as in mobile applications, game development, and embedded systems.
