Details

Currently, watchpoints are managed via Object.defineProperty on a per-instance basis. This means that it is impossible to have a single watchpoint for many instances of the same object.

  • local variables declared in a function
  • all instances of a class ...

One way to support local variables would be via a hidden breakpoint that pauses temporarily to add a watchpoint if it doesn't exist.
