Angular AOT Compiler vs JIT

What is the difference between Angular's AOT and JIT compilers?

AOT stands for Ahead-of-Time compilation, while JIT means Just-in-Time compilation. AOT compiles the application at build time, resulting in faster rendering and fewer runtime errors. JIT compiles the application in the browser at runtime, which can be slower but is useful for development.

What are the advantages of using AOT over JIT?

The advantages of AOT include faster rendering, smaller bundle sizes, and improved security since templates are pre-compiled. It also helps catch template errors during the build process rather than at runtime.

Are there any scenarios where JIT is preferred?

Yes, JIT is often preferred during development because it allows for quicker builds and easier debugging. It enables developers to see changes in real-time without needing to rebuild the entire application.

Can I switch between AOT and JIT in my Angular project?

Yes, you can switch between AOT and JIT by changing the build configuration in your Angular project. Use the ng build --prod command for AOT and ng serve for JIT.
