I need to reference the value of the same object on another value

Question

Hello i have an array of objects. Like this:

const obj = [{
   count: 10,
   value: count*2 // the previous count
}]

How can i reference 'count' on 'value' without having to find the index, or is a way to find the index of 'obj'?

Answer 1

You could take a getter with a reference to the same object.

const
    objects = [{
        count: 10,
        get value () { return this.count * 2; }
    }];

console.log(objects[0].value);
