+배열에서 주어진 값을 제거한 새로운 배열을 만들어요. 
+
+값이 같은지는 [SameValueZero](https://tc39.es/ecma262/multipage/abstract-operations.html#sec-samevaluezero) 기준으로 비교하기 때문에, `NaN`과도 사용할 수 있어요.
+
+## 인터페이스
+
+```typescript
+function without<T>(array: T[], ...values: T[]): T[];
+```
+
+### 파라미터
+
+- `array` (`T[]`): 값을 제거할 배열.
+- `values` (`...T[]`): 제거할 값.
+
+### 반환 값
+
+(`T[]`) 주어진 값을 제외한 새 배열.
+
+## Examples
+
+```typescript
+import { without } from 'es-toolkit/array';
+
+// 배열에서 지정된 값을 제거합니다
+without([1, 2, 3, 4, 5], 2, 4);
+// 결과 값: [1, 3, 5]
+
+// 배열에서 지정된 문자열 값을 제거합니다
+without(['a', 'b', 'c', 'a'], 'a');
+// 결과 값: ['b', 'c']
+
+// 지정된 값이 배열에 없는 경우를 처리합니다
+without([1, 2, 3], 4, 5);
+// 결과 값: [1, 2, 3]
+
+// 다른 유형의 값을 포함한 경우를 처리합니다
+without([1, '2', 3, '4'], 2, '4');
+// 결과 값: [1, '2', 3]

+# without
+
+Creates an array that excludes all specified values.
+
+It correctly excludes `NaN`, as it compares values using [SameValueZero](https://tc39.es/ecma262/multipage/abstract-operations.html#sec-samevaluezero).
+
+## Signature
+
+```typescript
+function without<T>(array: T[], ...values: T[]): T[];
+```
+
+### Parameters
+
+- `array` (`T[]`): The array to exclude values.
+- `values` (`...T[]`): The values to exclude.
+
+### Returns
+
+(`T[]`) A new array without the specified values.
+
+## Examples
+
+```typescript
+import { without } from 'es-toolkit/array';
+
+// Removes the specified values from the array
+without([1, 2, 3, 4, 5], 2, 4);
+// Returns: [1, 3, 5]
+
+// Removes specified string values from the array
+without(['a', 'b', 'c', 'a'], 'a');
+// Returns: ['b', 'c']
+
+// Handles cases where none of the specified values are in the array
+without([1, 2, 3], 4, 5);
+// Returns: [1, 2, 3]
+
+// Handles cases with different types of values
+without([1, '2', 3, '4'], 2, '4');
+// Returns: [1, '2', 3]
+```
