Added

• Query GitHub API to fetch co-author details by username #74 This will return the anonymous email.
• Migrating to TypeScript and so new files will be following TS and modified files will be migrated. See #82 and the follow-up work #83.

Example: rkotze is my GitHub username and is not stored in the co-authors file.

git mob rkotze

Example below shows mixing GitHub usernames with saved co-authors.

git mob rjk rkotze
