# destroy()

Destroys the component and cleans up memory. After a component that is declared in markup is no longer in use, the framework automatically destroys it and frees up its memory. If you create a component dynamically in JavaScript and that component isn't added to a facet (`v.body` or another attribute of type `Aura.Component[]`), you have to destroy it manually using `destroy()` to avoid memory leaks.

## Signature
