Tips for providing arguments in JavaScript

var Individual = { 
    name: "jana",
    retrieveName: function(cb) {
        cb();
        console.log("** "+this.name);
    }
}

var additionalIndividual = { name: "prabu"}

I possess 2 entities. I want to link "additionalIndividual" with the Individual entity and also pass a function as an argument.

I have attempted the following approaches, but they have not produced the desired outcome

Individual.retrieveName.apply(additionalIndividual, function(){})

Individual.retrieveName.apply(additionalIndividual)(function(){})

Utilize call to send a varying number of arguments to your function, or apply to send an array of arguments:

let Student = {
  name: "Sara",
  getGrade: function(callback) {
    callback();
    console.log("Grade: A");
  }
}

let anotherStudent = {
  name: "Tom"
}

Student.getGrade.call(anotherStudent, function () {})

Student.getGrade.apply(anotherStudent, [function () {}])

One way to assign a value to the getName property is by using an arrow function that returns the name parameter.

var Person = {
  name: "jana",
  getName: (obj) => obj.name
}

var anotherPerson = {
  name: "prabu"
}

Person.getName(anotherPerson);
console.log(Person);
