Making some perf improvements to a page and I have to support IE9 and below. And would you have it that they don’t support async tags for async loads. got it.
I’m about to do some more testing - but I feel I’m about to lose some perf to an old browser support request.
Do I have any options to async load some js files in IE9 and below? Figured i’d ask some pros whilst I go through the interweb.
Any inline JS will add a huge amount of time to maintaining the site.
The overhead of moving it ALL to a separate file is a very slight performance hit - too small to notice unless you attach thousands of external files to your page.
