An object constructor is a blueprint. Objects are supposed to represent real objects in the world. Think of programming is simulation of the real world, but text based.

 function Person(name,contact){
  this.name = name;
  this.contact = contact;
}

 var name = new Person("john",5445599);

console.log(name.name)
console.log(name.contact)

Be careful to keep constructors as proper casing.

It's basically to create grouping of variables and functions. In object oriented it's called properties and methods. Properties are like variables and methods are functions. I hope that helps.
