 * Joomla! Debug, especially its Stack Trace, and XDEBUG compatibly including links to the source in each trace
 * [Joomla J!Dump](https://extensions.joomla.org/extension/j-dump/) which works well for dumping within Joomla! components instead of using PHP echo and var_dump.

 There are [many other possibilities](https://docs.joomla.org/Setting_up_your_workstation_for_web_development), especially with the IDE, but this combination integrates well, and much of its features are native to the applications comprising it. This also applies to any other components used as examples in the videos and chapters accompanying them in this manual. Keep in mind as you progress through them the complexity of the components being shown as examples will increase. The directory tree will look more complex, and contain many additional files. However, they all share one thing in common which is the [MVC Paradigm](https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller); all follow its basic directory structure and naming conventions, including the files contained in it. This also includes the locations of the files. The code and necessary constructs specific to a Model, View or Controller for each to function and interconnect with each other and the Joomla! API at the most basic level are common to all, if developed using the MVC paradigm in its strictest sense.
