Find the list of mutual friends of two twitter users using their usernames using Twitter API
Currently, the rate limit set by Twitter is 15 requests per 15 minutes. Since maximum user count returned in a single request is 200, any request where the total count of friends of both the users exceeds 3000 (15*200) will immediately exhaust the rate limit quota! (For e.g. @WebSummit which has 26.4K friends)
- Normal case- All the mutual friends are displayed as clickable cards
- No mutual friends- Message is displayed
- Rate limit exceeded- Error message is displayed
- User not found- Error message is displayed
- Some unknown error- Error message is displayed
