# 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);
|
|
```
