JIT (Just-in-Time) -
1.      JIT compiles our app in the browser at run-time.
2.      Compiles before running
3.      Each file compiled separately
4.      No need to build after changing our app code and it automatically reflects the changes in your browser page
5.      Highly secure
6.      Very suitable for local development

AOT (Ahead-of-Time) -
1.      AOT compiles our app code at build time.
