# up.util.isGiven(value)

Returns whether the given argument is neither `undefined` nor `null`.

For the opposite of `up.util.isGiven()` see [`up.util.isMissing()`](https://unpoly.com/api/up.util.isMissing.md).

> #### Important
>
> Unpoly's concept of "given" does not correspond to JavaScript's concept of [truthy](https://developer.mozilla.org/en-US/docs/Glossary/Truthy). Empty strings or the number zero are not truthy, but _are_ considered to be "given".
