It's still present. JSON/JS parsing still has a delay. And in either case (as the author states) not everyone is using an iPhone over 5G. Heavy React apps are a miserable experience on low end Android phones, even when the connection is fast. I've seen JS/JSON parsing times in the multiple seconds.

There's 5 bars 5G and there's one bar 5G anyway... Citing connection types really is completely beside the point.

My old iPhone handles well react apps, but frequently freeze/crash on heavy advertised pages and pages with huge images/auto loading videos.

You don't think there's any palpable difference as long as the connection is any good?

I think there’s a palpable difference but many young developers have no concept of why.

Salesforce and SAP are not fast, even on that. But ubiquitous for building corporate platforms for their customers.

The vast majority of global users are not using iPhones.

Yes, that was kind of the point of my comment. Apparently not well made.

Read the article. Typical users had old browsers often with poor reception. One user was using a PlayStation Portable which had very limited WWW capability.

The person you are replying to is saying the PMs are using new phones on WiFi, not that the customers are.

Thank you.

"What, support Safari? Isn't that, like, less than 20%? And its standards support is abysmal! No, not worth my time, they can upgrade to a normal browser like everyone else."
