AOT Compilation
Ahead-of-Time (AOT) compilation is a compilation technique where source code or intermediate code is compiled into native machine code before the program is executed, typically during the build or deployment phase. This contrasts with Just-in-Time (JIT) compilation, which occurs at runtime. AOT compilation is commonly used in languages and frameworks to improve startup performance, reduce memory usage, and enable execution in environments where JIT compilation is restricted, such as mobile apps or web browsers.
Developers should use AOT compilation when optimizing for fast application startup times, predictable performance, and reduced runtime overhead, especially in resource-constrained environments like mobile devices or serverless functions. It is particularly valuable in web development with frameworks like Angular or in mobile app development with Flutter, where AOT can compile Dart or TypeScript code to efficient native binaries, enhancing user experience by eliminating JIT warm-up delays and improving security by reducing runtime code generation.
