{
  using resource = getResource();
} // always disposes resource

// vs.

{
  using stack = new DisposableStack();
  const resource = stack.use(getResource());
  stack.move(); // move resource out of `stack`
} // stack disposed but resource isn't

One of its uses is with class constructors, where you want the resources to be disposed if the constructor throws, but tracked with the class if everything succeeds:

class MyResource {
  #disposables;
  #resource1;
  #resource2;
  constructor(options) {
    using stack = new DisposableStack();
    this.#resource1 = stack.use(getResource1(options));
    this.#resource2 = stack.use(getResource2(options));
    // both succeeded
    this.#disposables = stack.move(); // move out of stack to store in #disposables
  } // stack is disposed

  [Symbol.dispose]() {
    this.#disposables.dispose();
  }
}
