AngularJS is a JavaScript framework that is maintained by Google and the open source community. Because of its ties to Google, and the popularity of the Google Chrome browser and Google’s Android platform, it makes sense to assume that it will be commonly supported and continue to be maintained and a strong choice for development for years to come.
“Lazy loading” is the term given to Ajax coding that loads content in a way that speeds up the rendering process on a website. Instead of waiting for all content to load from a database or web server, lazy loading allows you to display text and background components while other containers wait to load more resource-intensive content. As a result, the user sees content within seconds while other elements, such as reports or images, are still loading. It improves the perceived load times and engages users rather than lose them to poor performance.
