let tmpPromo = Object.assign({colspan: 0}, promo)? – Roy J Commented May 11, 2017 at 16:09 - Thanks a Lot @RoyJ – Ankit Kumar Gupta Commented May 11, 2017 at 18:15

Reset to default 7The object promo has had extensibility turned off via Object.preventExtensions (or seal or freeze). That means you cannot add new properties to it. Instead, you can make a new copy of it with new properties. A convenient way to do this is with Object.assign.
let tmpPromo = Object.assign({colspan: 0}, promo);
This starts with the anonymous object that defines colspan, copies properties from promo into it, and then returns the object (which we assign to tmpPromo).
