What is the difference between AOT and JIT in Angular?

What is the difference between AOT and JIT in Angular?

AOT stands for Ahead-of-Time compilation, while JIT stands for Just-in-Time compilation. AOT compiles the application at build time, resulting in faster rendering and smaller bundle sizes. 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?

The advantages of AOT include faster rendering, smaller bundle sizes, and early detection of template errors. It also improves security by preventing injection attacks.

Are there any downsides to using AOT?

Yes, the main downside is that AOT can increase the build time during development. Additionally, it may require more configuration compared to JIT.

When should I use JIT instead of AOT?

You should use JIT during development for faster build times and easier debugging. It's also useful for applications that require dynamic loading of components.

Can I switch between AOT and JIT easily?

Yes, you can switch between AOT and JIT by changing the build configuration in your Angular project. Just update the build command in your package.json.
