The bit clear-cache command removes the following:
- Bit's compiled code (compiled as part of V8's Just-in-Time compilation). Caching is optimized using the v8-compile-cache package. 
- Components cache on the filesystem: 
- The parsed component docs (e.g, prop types)
- The results for the dependency detection and resolution (saved in .git/bit/components/deps/).
- The scope's index file .git/bit/index.json, which maps the component-id:object-hash.
$ bit clear-cache the following cache(s) have been cleared: ✔ v8-compile-cache code ✔ components cache on the filesystem ✔ scope-index file
