I have an array of Objects and I would like to put numbers together in a specific field in those Objects. The Age field in each object.

this is what I did :

var users = [{name:'John',age:36},{name:'Max',age:21}]


var counter = 0;
var example = users.forEach(function(user){
counter += user.age
})

    ok, so what is the issue? – AT82 Aug 14 '19 at 11:38
  • could you add a sample of the array containing the user data so we can create code snippets to create working examples? – RainyRain Aug 14 '19 at 11:40

You can use reduce like that

let sum = users.reduce((a,b) => a.age + b.age, 0);

You can use simple for loop:

var users = [
  {
    age: 22
  },
  {
    age: 25
  },
  {
    age: 70
  }
];

var ageSum = 0;

for (var i = 0; i < users.length; i++) {
  ageSum += users[i].age;
}

console.log(ageSum);
