Within Chrome's Developer tool, there is a blue vertical line marked "DOMContent event fired", as well as a red line labeled "load event fired". Is it safe to assume that the "DOMContent event fired" signifies the initiation of inline JavaScript execution by the browser? Furthermore, does the "load event fired" signal the firing of the "onload" event?
"DOMContent Event" originates from webkit (which is utilized by Chrome) and serves as an equivalent to DOMContentLoaded msdn mdn.
The DOMContentLoaded event triggers when the parsing of the current page is finished; whereas the load (onload) event triggers once all files, including ads and images, have completed loading from all resources. DOMContentLoaded proves useful for connecting UI functionality to intricate web pages.

When the DOMContentLoaded event is triggered, it means that the document has finished loading and parsing all its content, excluding stylesheets, images, and subframes. To determine if a page is fully loaded, you can use the load event.
When the DOMContentLoaded event is triggered, it means that the document has been loaded and parsed completely, even before all stylesheets, images, and subframes finish loading (the load event can be used to determine when a page is fully loaded).
