Signature

function xor<T>(arr1: T[], arr2: T[]): T[];

Parameters

• arr1 (T[]): The first array.
• arr2 (T[]): The second array.

Returns

(T[]): An array containing the elements that are present in either arr1 or arr2 but not in both.

Examples

// Returns [1, 2, 5, 6]
xor([1, 2, 3, 4], [3, 4, 5, 6]);

// Returns ['a', 'c']
xor(['a', 'b'], ['b', 'c']);
