I am trying to speed up a website every way that I can. I decided to look into lazy loading which I have read about numerous times.
Lazy loading is basically not wasting time loading images that are off the screen, or out of the viewport.
This got me thinking, why do the browsers not do this for us? They would be better equipped to handle this than a JS developer. Especially since the browser is doing the rendering, it knows what it needs in order to display the screen.
