It works with the +long-established technologies of the web (HTML, CSS, and JavaScript) to make the development of +web apps easier and faster than ever before. + +One important way that angular simplifies web development is by increasing the level of abstraction +between the developer and most low-level web app development tasks. Angular automatically takes +care of many of these tasks, including: + +  * DOM Manipulation +  * Setting Up Listeners and Notifiers +  * Input Validation + +Because angular handles much of the work involved in these tasks, developers can concentrate more +on application logic and less on repetitive, error-prone, lower-level coding. + +At the same time that angular simplifies the development of web apps, it brings relatively +sophisticated techniques to the client-side, including: + +  * Separation of data, application logic, and presentation components +  * Data Binding between data and presentation components +  * Services (common web app operations, implemented as substitutable objects) +  * Dependency Injection (used primarily for wiring together services) +  * An extensible HTML compiler (written entirely in JavaScript) +  * Ease of Testing + +These techniques have been for the most part absent from the client-side for far too long. + +## Single-page / Round-trip Applications + +You can use angular to develop both single-page and round-trip apps, but angular is designed +primarily for developing single-page apps. Angular supports browser history, forward and back +buttons, and bookmarking in single-page apps. + +You normally wouldn't want to load angular with every page change, as would be the case with using +angular in a round-trip app. However, it would make sense to do so if you were adding a subset of +angular's features (for example, templates to leverage angular's data-binding feature) to an +existing round-trip app. You might follow this course of action if you were migrating an older app +to a single-page angular app.  |
