Lesson materials

These are some examples of previously created materials by mentors that you can use yourself, or for inspiration.

> Focus on having lots of in class exercises.

> DONT teach everything, let the students investigate topics on their own aswell!

> Focus on how to read documentation, google answers and google errors!!

> Teach towards the students being able to solve the homework

Remember to add the code you wrote in the class to the relevant class branch's class work folder. If the branch has not been created just create and push it :) If you dont have access, write to one from the core team. You can see an example below!

To find examples of what teachers have taught before go to the class branches in the classwork folder, Fx class 07

If you find anything that could be improved then please create a pull request! We welcome changes, so please get involved if you have any ideas!!!

Start VERY simple. Just a class that has few fields, no methods. Explain the diff from object to class. Explain instance etc. When they get that move on to class methods. Only teach extends if they really are on top of things otherwise just get them comfortable with classes :) if you can repeat a bit of promise, maybe when working with class that would be great.

    • Exercise
  • this
    • Refers to the instance of the class. Do go into too much detail and edge cases. Avoid mentioning bind, apply, etc unless you find it super important, the students will just forget it anyway!
  • Exercise
  • Extend (Only if time!)

At this point good coding practices is starting to get very important! Check our coding best practices and use these both when live coding but also in reviews.

Code inspiration

Constructor

class Comment {
    constructor(username, content, time) {
        this.username = username;
        this.content = content;
        this.time = time;
    }
}

Instance

const comment1 = new Comment('test', 'post', new Date());

Methods

class Comment {
    constructor(username, content, time) {
        this.username = username;
        this.content = content;
        this.time = time;
    }

    // Get help from students to write this method!
    getTimeSincePost() {
        return new Date().getTime() - this.time.getTime();
    }

    // Get help from students to write this method!
    hasSwearWord() {
        const swearWords = ['crap', 'damn'];
        const postWords = this.content.split(' ');
        const hasSwearWord = swearWords.find(swearWord => postWords.includes(swearWord));
  
        return Boolean(hasSwearWord);
    }
}

const comment1 = new Comment('test', 'post', new Date());

console.log(comment1.hasSwearWord())
comment1.content = 'shit crap'
console.log(comment1.hasSwearWord())
setTimeout(() => {
  console.log(comment1.getTimeSincePost())
}, 1000);

// data
// username, content, time

// functionality
// getTimeSincePost, hasSwearWord

Class post

class Post {
    // setup
    constructor(username, content, postTime, likes, comments, shares) {
        this.username = username;
        this.content = content;
        this.postTime = postTime;
        this.likes = likes;
        this.comments = comments;
        this.shares = shares;
    }

    addLike(username, time) {
        const like = {
            username: username,
            time: time
        };

        this.likes.push(like);
    }

    addComment(username, content, time) {
        this.comments.push(new Comment(username, content, time));
    }

    doShare() {

    }

    save() {

    }

    logThis() {
        console.log(this.username);
    }
}

const post1 = new Post('benna100', 'asd', '10/02/1019', [], [], []);
const post2 = new Post('habsdhjd', 'asdajhdb', '10/02/1019', [], [], []);

post1.addLike('bennaasdasd', '14:07');
console.log(post1.likes);

post1.addComment('ugg', 'Great post', '14:16');
console.log(post1.comments);

post1.logThis();
post2.logThis();

Exercises

1. Create a user class

The class should have 2 properties: firstName and lastName. Hint: Use this and constructor.

2. Create an instance of the class

Use the new keyword and assign the instance in a variable.

• Try to log out the instance of the User to the console.
• Try to log out the users firstName

3. Create a class method

The method should be called getFullName, and should return the combined first name and last name of the user. Use string concatenation or template literals. Remember to use the this keyword to access the attributes on the class instance.

Call the getFullName method and log the result to the console.

3. Creating a CV class

The CV that we will be making uses three classes: Job, Education and CV. The CV class we have made for you (with some missing functionality). The Job and Education classes you need to create.

Part 1:

Create the classes Job and Education.

• Job has five properties: id, title, description, startDate and endDate (the dates can be strings or actual Date objects).
• Education has six properties: id, title, school, address, startDate and endDate.

class Job {
   ///...
}

class Education {
   ///...
}

Part 2:

Now add the functionality for the methods in the CV class.

Remember: jobs and educations are just arrays of class instances. So use your array manipulation knowledge for the add and remove methods.

class CV {
  constructor(email) {
    this.jobs = [];
    this.educations = [];
    //this.email = ?
  }

  addJob(job) {
    // add functionality here
  }

  removeJob(job) {
    // add functionality here
  }

  addEducation(education) {
    // add functionality here
  }

  removeEducation(education) {
    // add functionality here
  }
}

Part 3:

1. Create a new CV instance using the new keyword, and save it in a variable called myCV.

2. Apply the methods you have created on the myCV object. Create a few Job and Education objects and add them to your CV.

3. Remove a job and an education from myCV.

4. Log myCV to the console, again, and check that the objects were removed correctly.

Part 4:

Add a method to the CV class called renderCV(). This method should render out the CV using HTML. Use document.getElementById("<id>") and document.createElement("<element>"), as well as element.appendChild(<element>) to build your HTML using JavaScript.
