How to use object constructor In Javascript

Using Object.create() method

Using JavaScript classes

JavaScript allows us to create the nested objects using constructor function which work as the initial starting point for the creation of the objects with the specific properties and behaviour. It can be used defining the each level of the nested objects hierarchy.

Example: This example shows the creating nested Object using object constructor.

Javascript




function company(name, location, courseObj) {
    this.name = name;
    this.location = location;
    this.course = courses;
}
 
function course(courseName) {
    this.courseName = courseName;
}
 
let courses = new course("DSA self paced course")
let companyName = new company("GeekforGeeks",
    "Noida", courses);
console.log(companyName);
 






                        









													
													
												

												
												

													
													
Output


company {
  name: 'GeekforGeeks',
  location: 'Noida',
  course: course { courseName: 'DSA self paced course' }
}
