Angular AoT (for Ahead-of-Time) compilation is the new feature added to Angular to significantly boost performance. Angular also works without AoT, just like AngularJS (version 1. X) used to. The compiler works in JIT mode (Just-in-Time), which means it runs on the user machine every time the app is loaded.
Also to know is, what is AOT compiler in angular?
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. Compiling your application during the build process provides a faster rendering in the browser.
Subsequently, question is, what is JIT and AOT in angular? The main differences between JIT and AOT in Angular are: Just-in-Time (JIT), compiles your app in the browser at runtime. Ahead-of-Time (AOT), compiles your app at build time on the server.
Similarly, it is asked, what does AOT stand for in angular?
Ahead-of-Time
What is Transpilation in angular?
The compiler takes the TypeScript code and converts it into JavaScript. This process is commonly referred to as transpiling, and since the TypeScript compiler does it, it’s called a transpiler. JavaScript as a language has evolved over the years with every new version adding new features/capabilities to the language.
