Re: Lighthouse scores: how to reduce render-blocking scripts
#2Kind of a lot of words for using Async, Defer, or IntersectionObserver. But this is a weird case of using IntersectionObserver. I'd rather use it for something like lazy-loading images[1]. They have a much higher download cost and will provide a much greater boost in performance than optimizing your JavaScript. Also, by placing all of your scripts at the bottom (save for a few at the top like Modernizr), you really don't need to worry too much about async vs defer.

I write the Lighthouse docs. This is not one of our docs.

It appears Google will be integrating lazy loading into the browser.[0]
In my almost 20 years of development experience, I find my todo list extremely long. And a core principle that has served me well is that if a feature is coming to the browsers for free, it's cheaper and easier to wait for the feature instead of spending real time/money building a cheap copy of it, and then having to rip it out a year later for the native feature.
"Feature patience" seems a fitting description.
I have recently used IntersectionObserver to replace scroll event functionality (modifying sticky positioned headers) and it's great for that, but I don't want to use it for lazy loading, seems like way to much work.
