Answer
AOT compiles Angular templates during the build process instead of in the browser.
It produces faster load times, smaller bundles, and more secure applications compared to JIT compilation.
Quick Answer
AOT compiles Angular templates and TypeScript to JavaScript at build time (not in the browser at runtime). Benefits: faster rendering (no template compilation in browser), smaller bundle (template compiler not shipped), earlier error detection (template errors caught at build time), and better security (no eval() at runtime). AOT is enabled by default in ng build --prod.
