how to use the intersectionwith function from lodash in javascript

To use the intersectionwith function from lodash in Javascript, you will first need to install the lodash library. You can do this by running the following command in your terminal:

index.tsx
npm install lodash

Once you have installed lodash, you can start using the intersectionwith function in your code. The intersectionwith function takes two or more arrays and a comparator function as its arguments. It returns an array of values that are present in all of the input arrays.

Here is an example of how to use the intersectionwith function:

index.tsx
const _ = require('lodash');

const arr1 = [{id: 1, name: 'John'}, {id: 2, name: 'Jane'}];
const arr2 = [{id: 2, name: 'Jane'}, {id: 3, name: 'Bob'}];

const comparator = (a, b) => a.id === b.id;

const intersection = _.intersectionWith(arr1, arr2, comparator);

console.log(intersection); // [{id: 2, name: 'Jane'}]

In the example above, we have two arrays arr1 and arr2, and a comparator function that checks if two objects have the same id property. We pass these arrays and the comparator function to the intersectionwith function, which returns an array containing the intersection of the two arrays based on the id property.

We store the result in the intersection variable and log it to the console. The output is an array that contains only the object that has the id value of 2, which is the intersection of the two arrays.
