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

There is actually only one Angular compiler. The difference between AOT and JIT is a matter of timing and tooling. With AOT, the compiler runs once at build time using one set of libraries; with JIT it runs every time for every user at runtime using a different set of libraries.
