Can someone help me figure out how to increase the values of two specific attributes within a class?

Question

Can someone help me figure out how to increase the values of two specific attributes within a class?

Currently facing a challenge with adjusting the number of likes and comments using increment for properties 'numberOfLikes' and 'comments'. Unsure whether to utilize a for loop or just the increment operator. Still new to coding, so apologies in advance.

/* Add to the existing skeleton of a Tweet class in the space provided below.

A tweet should consist of an (dynamic) author, content, timeStamp, numberOfLikes, and comments.
A tweet should be capable of incrementing the numberOfLikes and adding to the list of comments.

Create multiple instances of your Tweet and log them to the console. Ensure that the tweet object instances perform as expected. */

class Tweet {
    constructor(author, content, timeStamp, numberOfLikes, comments) {
      this.author = author;
      this.content = content;
      this.timeStamp = timeStamp;
      this.numberOfLikes = numberOfLikes;
      this.comments = comments;
 }
};


//This is code I experimented with, but it's not functioning

this.add = function(numberOfLikes){
  for(i = 0; i < numberOfLikes.length; i++){
    console.log("You have " + numberOfLikes + " likes");
  }
}

this.add = function(comments) {
  for(i = 0; i < comments.length; i++) {
    console.log("You have " + comments + " comments");
  }
}



var tweet1 = new Tweet("Rihanna", "Fenty Beauty", "12:31 A.M.", 120193, 6782);

Appreciate your help!

Answer №1

A tweet must have the ability to increase its number of likes.

To achieve this, a function should be implemented to increment the numberOfLikes.

Additionally, new comments can be added to the existing list.

The comments attribute is likely stored as an array. Therefore, it is essential to create a function that enables the addition of comments to the list.

class Tweet {
    constructor(author, content, timeStamp, numberOfLikes, comments) {
        this.author = author;
        this.content = content;
        this.timeStamp = timeStamp;
        this.numberOfLikes = numberOfLikes;
        this.comments = comments;
    }
    increaseNumberOfLikes() {
        this.numberOfLikes++
    }
    addComment(commentText) {
        this.comments.push(commentText)
    }
};

let tweet1 = new Tweet("The Weekend", "Some content", "15:31 P.M.", 9800, ["so cool", "do it again"])
tweet1.increaseNumberOfLikes()
tweet1.addComment("Great Song!")

console.log(tweet1)

You have the ability to develop functions that utilize += and array#push for increasing numbers and appending values to arrays.

Increasing likes:

incrementLikes(increment = 1) {
  this.numberOfLikes += increment
}

Adding a new comment to the array:

addComment(comment) {
  this.comments.push(comment)
}

An important aspect I observed in your message was the mention of this.comments being listed. Therefore, I incorporated that modification during the class initialization.

new Tweet("Rihanna", "Fenty Beauty", "12:31 A.M.", 120193, ["amazing", "wow"]);

Preview:

class Tweet {
  constructor(author, content, timeStamp, numberOfLikes, comments) {
    this.author = author;
    this.content = content;
    this.timeStamp = timeStamp;
    this.numberOfLikes = numberOfLikes;
    this.comments = comments;
  }
  
  incrementLikes(increment = 1) {
    this.numberOfLikes += increment
  }
  
  addComment(comment) {
    this.comments.push(comment)
  }
};

var tweet1 = new Tweet("Rihanna", "Fenty Beauty", "12:31 A.M.", 120193, ["amazing", "wow"]);

tweet1.incrementLikes()
console.log(tweet1.numberOfLikes)

tweet1.incrementLikes()
console.log(tweet1.numberOfLikes)

tweet1.addComment("This is a comment")
console.log(tweet1.comments)

var tweet1 = new Tweet("Rihanna", "Fenty Beauty", "12:31 A.M.", 120193, ["amazing", "wow"]);

tweet1.incrementLikes()
console.log(tweet1.numberOfLikes)

tweet1.incrementLikes()
console.log(tweet1.numberOfLikes)

tweet1.addComment("This is a comment")
console.log(tweet1.comments)

To implement prototypal functions within a class, follow this structure:

class Post {
  constructor(author, content, timeStamp, numberOfLikes, comments) {
    this.author = author;
    this.content = content;
    this.timeStamp = timeStamp;
    this.numberOfLikes = numberOfLikes;
    this.comments = comments;
  }
  like() {
    this.numberOfLikes++;
  }
  comment(comment) {
    this.comments.push(comment);
  }
}

const post1 = new Post("Taylor Swift", "Folklore Album", "10:45 P.M.", 98765, ["Can't stop listening to this masterpiece"]);

console.log(post1.numberOfLikes);
post1.like();
post1.like();
console.log(post1.numberOfLikes);
console.log(post1.comments);
post1.comment("Best album of all time!")
console.log(post1.comments);

.as-console-wrapper { min-height: 100%!important; top: 0; }

This method should do the trick. Make sure to enclose the function definitions within the class definition. I've also adjusted the function names to avoid conflicts.

class SocialPost {
    constructor(author, postContent, timestamp, likesCount, comments) {
      this.author = author;
      this.postContent = postContent;
      this.timestamp = timestamp;
      this.likesCount = likesCount;
      this.comments = comments;
 }

  addLikes(likes){
    this.likesCount += likes
  }

    addComments(newComment) {
      this.comments += newComment
  }
};


// Creating an initial social post instance
var firstPost = new SocialPost("Jennifer", "New product launch", "2:45 P.M.", 23042, 953);

// Applying modifiers
firstPost.addLikes(10)
firstPost.addComments(5)

// Checking if the variables have been updated
console.log(firstPost.likesCount)
console.log(firstPost.comments)
