/**
|
|
* 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 }]
