1. Open your command line and navigate to your repos directory (if you do not have a repos folder, then you can use mkdir repos to create one)
2. Use this template repository to start a new project in your repos folder: git clone <repo_name>
3. cd repo_name to navigate into your new repo directory
4. Start Visual Studio Code and select 'Open Folder'. Then select repo_name to open the folder in the editor (or just type code . in your terminal inside the repo directory)
5. Follow the instructions on the README.md file to complete exercises
6. Open the app.js file to get started

function watchTurorialCallback(callback, errorCallback) {
  let userLeft = false;
  let userWatchingLiveStream = true;

  if (userLeft) {
    errorCallback({
      name: "User Left",
      message: ":(",
    });
  } else if (userWatchingLiveStream) {
    callback("Thumbs up and Subscribe");
  }
}

watchTurorialCallback(
  (message) => {
    console.log(message);
  },
  (error) => {
    console.log(error.name + " " + error.message);
  }
);

• The above function can be replicated as a Promise.

1. Declare a variable watching and assign it a new promise object let watching = new Promise(); pass in a single callback let wathcing = new Promis ((resolve, reject)=> {

}); 2. Inside of the promise constructor, declare a variable named userWatchingLiveStream. let userWathcingLiveStresm = true;

3. Add a if/else conditional that checks if userWatchingLiveStream is true if (userWatchingLiveStream){ resolve ("Thumbs up and Subscribe!"); }else{ reject ("User left"); }

4. If userWatchingLiveStream is true, call the resolve method with "Thumbs up and Subscribe!" if from above

5. If false, call the reject method with "User left." else from above

• Once you have created your new promise:

1. Call watching and add a promise chain using .then and .catch
2. Pass in a function callback to .then that takes in a message and console.log's the message
3. Pass in a function callback to .catch that takes in an error and console.log's the error watching .then((result) => console.log(result)) .catch((error) => console.log(error));
