Thanks Aria/Rick for your replies!
I understand bean1, bean2 and bean3 are similar and they do the same thing.
What I was looking for is a standard way of creating data object but it
seems like it's more of a free-style and we can use any of the style to
create data objects.
Based on your replies, I think this is the best way to represent a data
object as it's just data and object can represent this data:
module.exports = {
name : '';
department : '';}
However I have noticed people using function() to create data objects and
then they just return an object inside the function (see below example)? Is
there any specific use case or reason on using function instead of using
just object literal?
module.exports = function() {
return {
name : 'abc',
city : 'sj'
}
}
