pullAllWith()

pullAllWith<T>(array, values, comparator): T[]

Removes all given values from array using a comparator function for equality.

DEPRECATED

Use differenceWith instead for immutable operations.

Reason:
Pithos design philosophy always favors immutability.

remarque

Mutates the array in place.

---

Type Parameters

T: T

The type of elements in the array.

---

Parameters

array: T[]

The array to modify.

values: readonly T[]

The values to remove.

comparator: (a, b) => boolean

The function invoked to compare elements.

---

Returns: T[]

The mutated array.

Example

// ❌ Deprecated approach (mutates array)
const array = [{ x: 1, y: 2 }, { x: 3, y: 4 }, { x: 5, y: 6 }];
pullAllWith(array, [{ x: 3, y: 4 }], (a, b) => a.x === b.x && a.y === b.y);
console.log(array); // [{ x: 1, y: 2 }, { x: 5, y: 6 }]

// ✅ Recommended approach (immutable)
const array = [{ x: 1, y: 2 }, { x: 3, y: 4 }, { x: 5, y: 6 }];
const result = differenceWith(array, [{ x: 3, y: 4 }], (a, b) => a.x === b.x && a.y === b.y);
console.log(result); // [{ x: 1, y: 2 }, { x: 5, y: 6 }]
console.log(array);  // unchanged

How it works?

Removes values from array using a comparator function (mutates).

Mutation Flow

Common Inputs

Array	Values	Comparator	Result
[{x:1}, {x:2}]	[{x:1}]	(a,b) => a.x === b.x	[{x:2}]

Deprecated: Use differenceWith() from Arkhe for immutable operations.

Use Cases

Remove with custom comparator 📌

Remove values using custom equality comparison.

#remove#filter#comparator#custom#objects

const users = [{ id: 1 }, { id: 2 }, { id: 3 }];
const toRemove = [{ id: 2 }];
const result = users.filter(u => 
  !toRemove.some(r => r.id === u.id)
);
// [{ id: 1 }, { id: 3 }]

Filter by property

Remove objects matching specific criteria.

#filter#property#match#objects

const products = [
  { sku: 'A1', stock: 0 },
  { sku: 'B2', stock: 5 },
  { sku: 'C3', stock: 0 }
];
const outOfStock = products.filter(p => p.stock > 0);
// [{ sku: 'B2', stock: 5 }]
