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.
