The code in this gist allows you to get the list of linkedin connections and followers you have.

functionToCompare.js

/*This checks the names in the connections list against the names in the followers list.
And returns the list of names of people that are not in the followers list*/
function checkConnectionsAgainstFollowers(followers, connections) {
    let connectedButNotFollowing = [];
    for (let connection of connections) {
        if (!followers.includes(connection)) {
            connectedButNotFollowing.push(connection);
        }
    }
    return connectedButNotFollowing;
}

// run this on node using ``node functionToCompare.js`` or just run in the console.

functionToCompare.py

# python 3.9.5

def checkConnectionsAgainstFollowers(followers: list[str], connections: list[str]) -> list[str]:
    """This checks the names in the connections list against the names in the followers list. 
    And returns the list of names of people that are not in the followers list"""

    connectedButNotFollowing: list[str] = []
    
    for connection in connections:
        if connection not in followers:
            connectedButNotFollowing.append(connection)

    return connectedButNotFollowing

We're making use of the DOM here.

One might be curious as to where these class names come from. These are the classes of the elements that have your follower/connection name as their innerText.

A simple DOM and style inspecting can help you in finding them.
