Then you can import the function in your TypeScript file and use it like this:

index.ts
import { xorBy } from 'lodash';

const arr1 = [1, 2];
const arr2 = [2, 3];

const result = xorBy(arr1, arr2, (item) => item);

console.log(result); // Output: [1, 3]

In this example, we are using the xorBy function to compare two arrays (arr1 and arr2) and return the symmetric difference between them. The function takes three arguments:

  • The first and second arguments are the arrays to compare.
  • The third argument is a function that is used to identify the values to compare. In this case, we are using the identity function ((item) => item), which means that we compare the actual values in the arrays.

Finally, we log the result to the console, which should show [1, 3].
