Can anyone explain object in javascript in detail?


Replace this line with your code.


Such an answer is extensive to write. Thankfully other people/organizations did this for us, for example MDN- javascript objects


if i put this code why show only int value?
string value are not there in output

var myCar = new Object();
myCar.make = "Ford";
myCar.model = "Mustang";
myCar.year = 1969;


Well, normally nothing would be printed, that is codecademy console, as explained in detail by haxor here
