JavaScript on Fandom Developers Wiki is used for creating userscripts that enhance user experience in many ways. In order to maintain high quality code and usability of userscripts, there are certain rules and guidelines that apply to code submitted to Fandom Developers Wiki:
- Wiki policy — outlines the basic rules scripts must adhere to.
- Maintainership rules — define who mainly has the say in deciding what script's content will be.
- Coding conventions — show recommended standards of writing code on Fandom Developers Wiki.
- Interventions — a way to semi-bypass maintainership rules in case of a major breaking change to Fandom's code that requires mass-maintenance actions.
