Eliminate items from a list that have duplicate properties

I have a collection of objects, each with a unique NAME property. However, there are duplicates in the collection where some objects share the same NAME.

const arr = [
    {name: "x", place: "a", age: "13" },
    {name: "x", place: "b", age: "14" },
    {name: "y", place: "c", age: "15" },
    {name: "d", place: "d", age: "16" }
]

Is there a way to filter this collection so that only one object remains per unique NAME? Any duplicates should be removed from the list.

The desired output should look like:

const arr = [
    {name: "x", place: "a", age: "13" },
    {name: "y", place: "c", age: "15" },
    {name: "d", place: "d", age: "16" }
]

or

const arr = [
    {name: "x", place: "b", age: "14" },
    {name: "y", place: "c", age: "15" },
    {name: "d", place: "d", age: "16" }
]

Can Lodash be utilized for this task?

Answer №1

If you're looking for a way to easily remove duplicates in an array based on a specific property, look no further than the `uniqBy` function from Lodash:

const _ = require('lodash');
const uniqueResults = _.uniqBy(array, 'property');
