When you have the required keys and tokens you can check whether the user is following another user in twitter by using the Twitter API. I am using TweetSharp c# library to perform this task. I have tried with below code and worked for me. If you ever want to do it, try using below code segment.

_consumerKey = Your consumer key
_consumerSecret = Your consumer secret
_token = Authorized token
_tokenSecret = Token secret

TwitterService service = new TwitterService(_consumerKey, _consumerSecret);
service.AuthenticateWith(_token, _tokenSecret);
var user =  service.VerifyCredentials(new VerifyCredentialsOptions());
var twitterFriendship = service.GetFriendshipInfo(new GetFriendshipInfoOptions() { SourceScreenName = user.ScreenName, TargetScreenName = "profileName goes here" });

Now you have the required object and you check it using below condition.

(twitterFriendship.Relationship.Source.Following && twitterFriendship.Relationship.Target.FollowedBy)?true:false;

Cmder console for windows

Found this console for windows. It is a combination of ConEmu and Clink. This is a portable application and need to add into our PATH( not mandatory). With the full version, you have git for windows installed. So just download, unzip and run. We can add custom themes for cmder. This support multiple tabs with different users. If you are working with vs code, you can integrate cmder as the terminal. You can downlod cmder from here.

Different between Local Storage, Session Storage and Cookies

There are many places over the internet which describe and explain this in details. I thought to gather few of them into one place.

Local Storage

This is a part of the web storage API.
Store data as key value pairs.
Can share between sub domains.
Store data in user’s browser and can be inspected by developer tools.
Large amounts of data can be stored locally, without affecting website performance.
Information will never transferred into the server.
From all pages can store and access data.
Support up to 10MB storage for most of modern browsers.
No expiration.

// Save data into local storage
let key = 'Key 1';
localStorage.setItem(key, 'damith');

// Get data from local storage
let myItem = localStorage.getItem(key);

// Update excising value 
localStorage.setItem(key, 'damithw');

// Remove key from local storage
localStorage.removeItem(key);

// Clear all local storage data for current origin
localStorage.clear();

Session Storage

This is a part of the web storage API.
Store data as key value pairs.
Get cleared after page session ends.
Opening page in different tab or window cause a new session to be initiated.
Information will never transferred into the server.
Support up to 10MB storage for most of modern browsers.
Expire after browser or tab closed.

// Save data to sessionStorage
sessionStorage.setItem('name', 'damith');

// Get saved data from sessionStorage
var data = sessionStorage.getItem('name');

// Remove saved data from sessionStorage
sessionStorage.removeItem('name');

// Remove all saved data from sessionStorage
sessionStorage.clear();

Cookies

We can set expiration period to each cookie
The browser may store it and send it back with the next request to the same server
Keep stateful information for the stateless HTTP protocol. ( Ex: User logged-in )
Mainly used for
- Session management – Logins, shopping carts
- Personalization – Themes, User preferences
- Tracking – Recording and analyzing user behavior
Stored in client’s browser
Sent with every request
Two types of cookies are
- Session cookies – It is deleted when client shut down
- Permanent cookies – Can have expiry date
Domain and path directives define the scope of the cookie
Should consider about Session hijacking and XSS
