![]() Ahead of Time compilation helps in tracing errors at an earlier stage.The reason behind this fast rendering is that the compilation being performed just before rendering the app is now performed a lot earlier with AOT. Programmers gain the advantage of rendering applications faster.AOT compilation makes the size of the Angular framework shrink to half of the size of itself, and, therefore, the application to be served becomes smaller in size as well. ![]() With AOT, developers have smaller application sizes to serve to the browser.Here are a few of the most important advantages of Ahead of Time compilation: Advantages of AOT over JIT CompilationĪOT has some beneficial advantages over JIT. With JIT, the code gets compiled at runtime, while AOT compiles the code beforehand. The difference only lies in when the compilation occurs. ![]() It significantly decreases the efforts of the runtime engine, as it frees the interpreter not to worry about the compilation of different website assets before they are shipped to the browser.Īt the end of the day, the aim of both AOT and JIT approaches is the same – to compile high-level language code into native code. Like JIT, AOT also compiles high-level language code (JavaScript) into a binary code form to make it executable on the browser. With this approach, as its name implies, compilation is performed before the program runs in the browser. What is Ahead of Time (AOT) Compilation in Angular?ĪOT (Ahead of Time) is an act of compilation and it is not just specific to Angular. In this way, JIT performed the compilation of code as it was being delivered to the browser. When the user accessed the Angular app in their browser, it fetched all the required files from the server and then compiled the JavaScript code into binary code format, which could then be executed by the browser’s interpreter. In Angular’s older versions, JIT was the default compilation option that compiled your app while it was running in the browser. As its name suggests, the compilation is performed at runtime when the code is running in the browser. Just in Time (JIT) compilation is one of the compilation approaches Angular uses to compile code. Read: Best Online Courses to Learn HTML What is Just in Time (JIT) Compilation in Angular? Let’s begin by first briefly discussing the two compilation processes. ![]() ![]() In this web development tutorial, we will be discussing the concept of these two compilation approaches, examine how AOT works with Angular code, and see its impact on the performance of the app while it runs on the browser. We will discuss both of these compilation methods in detail throughout this guide. With the advent of Angular CLI (Command Line Interface) tools, however, it is now possible to use AOT (Ahead of Time) compilation instead, which makes it easier to optimize your Angular apps. The first one is the Just in Time (JIT) compilation, on which Angular relied previously. The compilation process consists of two approaches. If you have ever examined an Angular app’s file structure, you would find a lot of HTML, CSS, and JavaScript templates that all work together and get compiled to render a well-crafted web application. ![]()
