There are industries that use real robust tooling to run banks, build databases, control surgical robots. They don't choose Javascript, it has all the robustness of a wet noodle.

Desktop and Mobile application are reasonably robust, have very complex software and could do everything Facebook does trivially. All this 'robust tooling' has evolved because we are trying to shove an application into a browser, and despite decades of effort. it still kinda sucks.

If Apple, Microsoft and various distributions of Linux pulled the finger out of their collective asses and agreed on a half-decent, cross-platform GUI software package in 2005, none of this JS madness would exist.
