disposableStack[Symbol.dispose]()

Examples

Declaring a stack with using

The Symbol.dispose method is intended to be automatically called in a using declaration.

  const resource = disposer.use(new Resource());
  resource.doSomething();
  // stack is disposed here immediately before the function exits
  // which causes the resource to be disposed
}
