Cloning an Object in Node.js

Question

What is the best way to clone an object in node.js

e.g. I want to avoid the situation where:

var obj1 = {x: 5, y:5};
var obj2 = obj1;
obj2.x = 6;
con         


        

Answer 1

You can prototype object and then call object instance every time you want to use and change object:

function object () {
  this.x = 5;
  this.y = 5;
}
var obj1 = new object();
var obj2 = new object();
obj2.x = 6;
console.log(obj1.x); //logs 5

You can also pass arguments to object constructor

function object (x, y) {
   this.x = x;
   this.y = y;
}
var obj1 = new object(5, 5);
var obj2 = new object(6, 6);
console.log(obj1.x); //logs 5
console.log(obj2.x); //logs 6

Hope this is helpful.
