[Home](./index.md) > [@apextoaster/js-utils](./js-utils.md) > [hasItems](./js-utils.hasitems.md) ## 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. Signature: ```typescript export declare function hasItems(val: Optional>): val is Array; ``` ## Parameters | Parameter | Type | Description | | --- | --- | --- | | val | [Optional](./js-utils.optional.md)<Array<T>> | | Returns: val is Array<T>
