WordPress is built on an event-driven engine. Through the Plugin API, we developers are given the power to extend, reorder, remove, and change the behavior of WordPress, plugins, and themes. Success in WordPress begins right here with a solid fundamental mastery of the event-driven system.
As a professional developer, it is essential that you master the event-driven (hook) system in WordPress. It’s at the center of everything we do, allowing us to interact with or hook into each other’s products using functions such as
add_filter. Deeply learning about the inter-workings of this engine will accelerate not only your WordPress knowledge but also you programming, PHP, and programmatic and logical thinking.
