/**
* Removes all specified values from an array using an iteratee function.
*
* This function changes `arr` in place.
* If you want to remove values without modifying the original array, use `differenceBy`.
*
* @template T
* @param arr - The array to modify.
* @param valuesToRemove - The values to remove from the array.
* @param getValue - The key of the property to match against each element.
* @returns The modified array with the specified values removed.
*
* @example
* // Using a iteratee function
* const items = [{ value: 1 }, { value: 2 }, { value: 3 }, { value: 1 }];
* const result = pullAllBy(items, [{ value: 1 }, { value: 3 }], obj => obj.value);
* console.log(result); // [{ value: 2 }]
*
* // Using a property name
* const items = [{ value: 1 }, { value: 2 }, { value: 3 }, { value: 1 }];
* const result = pullAllBy(items, [{ value: 1 }, { value: 3 }], 'value');
* console.log(result); // [{ value: 2 }]
