Compare objects in JavaScript

Question

I have next object:

rows = [
  {
    name: "user1",
    previlege: "Filtering"
  },
  {
    name: "user2",
    previlege: "Reportering"
  },
  {
    name: "user3",
    previlege: "Filtering"
  }
]

And another object:

selected = {
  name: "user1",
  previlege: "Filtering"
}

I want filter rows and delete object which matched, so I need to compare them. I tried like this:

rows.filter(function(object) {
  return JSON.stringify(object) !== JSON.stringify(selected);
});

But it doesn`t work. How can I delete this matched object?

Are you sure you want to compare through JSON.stringify(), though? If you want to filter out the object with the same name property, but it has a different previlege property, it wouldn't work. — dodov

You could turn an object into a string and then do a string comparison but you could also just compare the name and privilege properties, which would probably be faster and potentially more reliable. — James

Are you taking the result in a new variable like var ans=rows.filter? — Pankaj Shukla

If you want to remove the element from the array you can try to store the result of filter into a new array

newArray = rows.filter(function(object) {
  return JSON.stringify(object) !== JSON.stringify(selected);
});

rows = newArray;

Or simply rows = rows.filter(...).

yeah that works too, just trying to be more explicit :)
