DasSur.ma – The 9am rush hour

Why JavaScript is a real performance bottleneck:

Rush hour. The worst time of day to travel. For many it’s not possible to travel at any other time of day because they need to get to work by 9am.

This is exactly what a lot of web code looks like today: everything runs on a single thread, the main thread, and the traffic is bad. In fact, it’s even more extreme than that: there’s one lane all from the city center to the outskirts, and quite literally everyone is on the road, even if they don’t need to be at the office by 9am.
