None of that is the fault of Javascript, it's on the people building them. This is logically correct, but I don't think it's true in the spirit of the argument

None of that is the fault of Javascript, it's on the people building them. This is logically correct, but I don't think it's true in the spirit of the argument. Browsers makes it very easy to deploy a broken website. They're incredibly tolerant of faults. Consequently there's no accountability for problems. If browsers didn't try to display broken apps in a sort-of-working-but-not-really way there'd be a lot fewer broken apps.
