How to use Lodash Library In Javascript
Using the Lodash library’s uniqWith function with a custom comparison function compares objects for uniqueness. It returns an array of unique objects by comparing their properties or values, allowing for flexible and efficient handling of object uniqueness.
Example: In this example we use Lodash’s _.uniqWith and _.isEqual to remove duplicate objects from the array.
const _ = require('lodash');
let arr = [
{ id: 1, name: 'Alice' },
{ id: 2, name: 'Bob' },
{ id: 1, name: 'Alice' }
];
let uniqueObjects = _.uniqWith(arr, _.isEqual);
console.log(uniqueObjects);
Output
[
{ id: 1, name: 'Alice' },
{ id: 2, name: 'Bob' }
]
