2:13:30 ........................ In JavaScript, when you use the spread syntax (...) on an object like {0:'a', 1:'b', 2:'c'}, it only works for iterables like arrays. Objects are not directly iterable with spread syntax.If you want to convert the object a into an array of its values, you should use Object.values() method.

2:13:30 ........................ In JavaScript, when you use the spread syntax (...) on an object like {0:'a', 1:'b', 2:'c'}, it only works for iterables like arrays. Objects are not directly iterable with spread syntax.If you want to convert the object a into an array of its values, you should use Object.values() method.
it only works when their is length of the object also present else it will not work in all two case which you are talking about
