Sometimes, we want to get the last item in a JavaScript object.

In this article, we’ll look at how to get the last item in a JavaScript object.

Get the Last Item in a JavaScript Object

To get the last item in a JavaScript object, we can use the Object.entries method to get the key-value pair arrays of an object in an array.

Therefore, we can use it to get the last item of the JavaScript object.

For instance, we can write:

const obj = {
  'a': 'apple',
  'b': 'banana',
  'c': 'carrot'
}
const entries = Object.entries(obj)
const [last] = entries.slice(-1)
console.log(last)

We have the obj object that we want to get the last property from.

Next, we call Object.entries with obj to get an array of key-value pair arrays of obj .

Then we call slice with -1 to return an array with the last entry of entries .

And we destructure that and assign it to last .

Therefore, last is:

["c", "carrot"]

Conclusion

To get the last item in a JavaScript object, we can use the Object.entries method to get the key-value pair arrays of an object in an array.

Therefore, we can use it to get the last item of the JavaScript object.
