var person = new Object();

console.log(person) //Result: Object {name: "Manoj"} 

var ages = new Array(10);
console.log(ages) // Result: [,,,,,,,,,,] gotcha!

// Always use JSON format. 
var person = {
  name: 'Manoj'
}
console.log(person) //Result: Object {name: "Manoj"} (This calls new behind the scene and return new object)
