What is the difference between AOT and JIT in Angular CLI?

What is the difference between AOT and JIT in Angular CLI?

AOT stands for Ahead-of-Time compilation, while JIT stands for Just-in-Time compilation. AOT compiles your application at build time, which can lead to faster rendering in the browser. JIT compiles the application in the browser at runtime, which can be useful for development but may slow down performance in production.

What are the advantages of using AOT over JIT?

The advantages of AOT include faster rendering, smaller bundle sizes, and earlier detection of template errors. It also improves security by not allowing the execution of arbitrary code in the browser.

Are there any downsides to using AOT?

Yes, AOT can increase the build time and may require more initial setup. Additionally, some dynamic features may be limited compared to JIT.

When should I choose JIT over AOT?

You might choose JIT during development for faster builds and easier debugging. It's also useful if your application relies heavily on dynamic components.
