JIT Compiler vs AOT Compiler

Just-in-time (JIT) mode is a good choice during development. Consider using the ahead-of-time (AOT) mode for production apps.

The Angular Just-in-time (JIT) compiler provides bootstrapping method of compiling components and modules in the browser and launching the application dynamically.

The Angular Ahead-of-Time (AOT) compiler converts your Angular HTML and TypeScript code into efficient JavaScript code during the build phase before the browser downloads and runs that code.
