Adding elements to object

Question

I need to populate a json file, now I have something like this:

{\"element\":{\"id\":10,\"quantity\":1}}

And I need to add another \"elemen

Answer 1

I was reading something related to this try if it is useful.

1.Define a push function inside a object.

let obj={push:function push(element){ [].push.call(this,element)}};

Now you can push elements like an array

obj.push(1)
obj.push({a:1})
obj.push([1,2,3])

This will produce this object

obj={
 0: 1
 1: {a: 1}
 2: (3) [1, 2, 3]
 length: 3
}

Notice the elements are added with indexes and also see that there is a new length property added to the object.This will be useful to find the length of the object too.This works because of the generic nature of push() function
