Before anything can happen in a browser, it must first know where to go. There are multiple ways to get somewhere: entering a URL in the address bar, clicking (or tapping) on a link on a page or in another app, or clicking on a favorite. No matter the case, these all result in what’s called a navigation. A navigation is the very first step in any web interaction, as it kicks off a chain reaction of events that culminates in a web page being loaded.
