What's the difference between the `DOMContentLoaded` and `load` events?

✓Correct answer: DOMContentLoaded fires when the HTML is parsed and deferred scripts ran; load waits for images, styles and other resources too
2DOMContentLoaded waits for all images; load only waits for HTML
3load fires first, then DOMContentLoaded

Explanation

Code that needs the DOM can start at DOMContentLoaded; load is later and depends on every subresource.
