One company found that too much JavaScript costs them $700,000 per year, per kilobyte. (thenewstack.io)

This was more interesting than I expected. Though they didn’t clarify why it costs $700,000, given the context I assume it’s customers on slower devices/connectivity leaving rather than something like bandwidth?

Often, it boils down to one common problem: Too much client-side JavaScript. This is not a cost-free error. One retailer realized they were losing $700,000 a year per kilobyte of JavaScript, Russell said.

“You may be losing all of the users who don’t have those devices because the experience is so bad,” he said.

They just didn't link to the one retailer's context. But it's "bring back old reddit" energy directed at everything SPA-ish.

edit to give it a little personal context: I was stuck on geosat internet for a little while and could not use amazon's site across the connection. I'm not sure if they're the retailer mentioned. But the only way I could make it usable was to apply the ublock rule *.images-amazon.com/*.js^ described here.

What really stunk about it was that if you're somewhere where geosat is/was the only option, then you're highly dependent on online retail. And knowing how to manage ublock rules is not exactly widespread knowledge.
