Editing Mutator method (section)

===JavaScript===
In this example constructor-function <code>Student</code> is used to create objects representing a student with only the name stored.
<syntaxhighlight lang="javascript">
function Student(name) {
  var _name = name;

  this.getName = function() {
    return _name;
  };

  this.setName = function(value) {
    _name = value;
  };
}
</syntaxhighlight>
Or (using a deprecated way to define accessors in Web browsers):<ref>{{Cite web|title=Object.prototype.__defineGetter__() - JavaScript {{!}} MDN|url=https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/__defineGetter__|access-date=2021-07-06|website=developer.mozilla.org|language=en-US}}</ref>
<syntaxhighlight lang="javascript">
function Student(name){
    var _name = name;
   
    this.__defineGetter__('name', function() {
        return _name;
    });
   
    this.__defineSetter__('name', function(value) {
        _name = value;
    });
}
</syntaxhighlight>
Or (using prototypes for inheritance and [[ES6]] accessor syntax):
<syntaxhighlight lang="javascript">
function Student(name){
    this._name = name;
}

Student.prototype = {
    get name() {
        return this._name;
    },
    set name(value) {
        this._name = value;
    }
};
</syntaxhighlight>
Or (without using prototypes):
<syntaxhighlight lang="javascript">
var Student = {
    get name() {
        return this._name;
    },
    set name(value) {
        this._name = value;
    }
};
</syntaxhighlight>
Or (using defineProperty):
<syntaxhighlight lang="javascript">
function Student(name){
    this._name = name;
}
Object.defineProperty(Student.prototype, 'name', {
    get: function() {
        return this._name;
    },
    set: function(value) {
        this._name = value;
    }
});
</syntaxhighlight>
