Asynchronous JavaScript Loader


Asynchronous JavaScript loading provides a mechanism to load JavaScript files asynchronously. It helps in improving the performance of the web applications / browser. In addition to this, it also provides a way to encapsulate JavaScript files in many different files, similar to Java where keywords like import, package and class are used for this purpose. Using the traditional synchronous method of loading the files may affect the performance and usability of the applications that have more dependencies (load multiple JavaScript files at runtime).
