The problems I've found with this approach are: 1) It is hard to write clear explanations of things that you don't understand. 2) It adds another project to your plate. If you don't actually allocate time for this project from what you are currently doing, it won't get done well and it will distract you from what your primary responsibility is. EDIT: So, OP would need to convince the product owner that he should spend his time on docs rather than javascript.
