# Mozilla ESLint SpiderMonkey JS This plugin adds a processor and an environment for the SpiderMonkey JS code. ## Processors The processor is used to pre-process all `*.js` files and deals with the macros that SpiderMonkey uses. ## Environments The plugin provides a custom environment for SpiderMonkey's self-hosted code. It adds all self-hosting functions, error message numbers, and other self-hosting definitions as global, read-only identifiers.
