how to use the xorby function from lodash in javascript

To use the xorBy function from lodash in JavaScript, you first need to import it into your project. You can do this using the import statement:

index.tsx
import xorBy from 'lodash/xorBy';
34 chars
2 lines

Once you have imported the function, you can use it to perform an XOR operation on two or more arrays. The xorBy function takes two or more arguments:

  • The first argument is an array of values that you want to compare with the other arrays.
  • The remaining arguments are arrays that you want to compare with the first array.

Additionally, xorBy function also takes a function that determines how to compare the values in each array. This function should take a single argument and return a value that will be used to compare against the other arrays. For example:

index.tsx
const array1 = [1, 2, 3, 4];
const array2 = [3, 4, 5, 6];
const array3 = [4, 5, 6, 7];

const result = xorBy(array1, array2, array3, item => item);

console.log(result); // [1, 2, 7]
183 chars
8 lines

In this example, the xorBy function compares the three arrays and returns an array containing elements that exist in only one of the arrays. The function used to compare the values simply returns the value itself (i.e. the identity function), so each value is compared directly with the values in the other arrays. The resulting array contains 1, 2, and 7, which are the values that exist in only one of the three input arrays.
