Based on your list there is an opportunity to define stage -1 of error handling sanity, the Eval-Rinse-Reload loop, as implemented by FuckItJS, the original Javascript Error Steamroller: https://github.com/mattdiamond/fuckitjs

> Through a process known as Eval-Rinse-Reload-And-Repeat, FuckItJS repeatedly compiles your code, detecting errors and slicing those lines out of the script. To survive such a violent process, FuckItJS reloads itself after each iteration, allowing the onerror handler to catch every single error in your terribly written code.

> [...]

> This will keep evaluating your code until all errors have been sliced off like mold on a piece of perfectly good bread. Whether or not the remaining code is even worth executing, we don't know. We also don't particularly care.
