Just-in-Time (JiT) vs Ahead-of-Time (AoT) compilation in Angular

Question

I was referring this documentation and came across the compilation concept. One can use either JIT or AOT compilation. However, I found it very brief and need to know follow

Answer 1

JIT (Just-in-Time Compilation)

Just-in-Time (JIT) is a type of compilation that compiles your app in the browser at runtime.

ng build
ng serve

AOT (Ahead-of-Time Compilation)

Ahead-of-Time (AOT) is a type of compilation that compiles your app at build time.

ng build --aot
ng serve --aot
