Deep copying custom function

index.js

function cloneObject(object) {
  let copy;
  
  if (Array.isArray(object)) {
  	copy = [];
  } else {
    copy = {};
  }
   
  
    for(let key in object) {
        if(typeof(object[key]) === "object" && object[key] !== null ){
            copy[key] = cloneObject(object[key]);
        } else {
            copy[key] = object[key];
        }
    }
    return copy;
}

let original = {
	name: 'Sarah',
	age: 35,	
	family: [
    	{ name: 'Mark', age: 29 },
    	{ name: 'Linda', age: 33 }
	] 
}

let clonedObject = cloneObject(original);

console.log(original);
console.log(clonedObject);


// each object has distinct reference
console.log('original === clonedObject', original === clonedObject);		// false
