# takeWhile Returns a new array containing the leading elements of the provided array that satisfy the provided predicate function. It stops taking elements as soon as an element does not satisfy the predicate. ## Signature ```typescript function takeWhile<T>(arr: T[], shouldContinueTaking: (element: T) => boolean): T[]; ``` ### Parameters - `arr` (`T[]`): The array to take elements from. - `shouldContinueTaking` (`(item: T) => boolean`) The predicate function that is called with each element. Elements are included in the result as long as this function returns true. ### Returns (`T[]`) A new array containing the elements taken from the beginning while the predicate returns `true`. ## Examples ```typescript // Returns [1, 2] takeWhile([1, 2, 3, 4], x => x < 3); // Returns [] takeWhile([1, 2, 3, 4], x => x > 3); ```
