I am interested in creating a ranking system in JavaScript using JSON data based on points

I have a desire to create the following:

var users = {jhon: {name: 'jhon', points: 30}, markus:{name: 'Markus', points: 20}};

// I want it to return like this 1. Jhon with number of points: 30

// 2. Markus with number of points: 20

Can someone guide me on how to achieve this?

Answer №1

One way to iterate through all the properties of an object is by using the for ( - in -) method on the object itself, such as the users object.

Check out the example below:

var users = {
  jhon: {
    name: 'jhon',
    points: 30
  },
  markus: {
    name: 'Markus',
    points: 20
  }
};

for (user in users) {
  console.log(user + " with number of points: " + users[user]['points']);
}

Answer №2

To achieve the desired outcome, utilize Object.values() to access each value, then use array#forEach for iteration. Utilize Template literals for generating the specific string required.

var users = {alice: {name: 'Alice', points: 40}, bob:{name: 'Bob', points: 25}},
    result = Object.values(users).forEach((v,i) => console.log(`${i+1}. ${v.name} with total points: ${v.points}`));
