## hasItems() function
|
|
|
|
Test if a value is an array with some items (length > 0).
|
|
|
|
This is not a general replacement for `.length > 0`<!-- -->, since it is also a typeguard: `if (hasItems(val)) else { val }` will complain that `val` is `never` in the `else` branch, since it was proven not to be an array by this function, even if `val` is simply empty.
|
|
|
|
<b>Signature:</b>
|
|
|
|
```typescript
|
|
export declare function hasItems<T>(val: Maybe<Array<T>>): val is Array<T>;
|
|
```
