+* `resource` {Object} Any non-null object tied to the abortable operation and held weakly.
+  If `resource` is garbage collected before the `signal` aborts, the promise remains pending,

-aborted, the returned promise shall remain pending indefinitely.
+Listens to abort event on the provided `signal` and returns a promise that resolves when the `signal` is aborted.
+If `resource` is provided, it weakly references the operation's associated object,
+so if `resource` is garbage collected before the `signal` aborts,
+then returned promise shall remain pending.
+This prevents memory leaks in long-running or non-cancelable operations.

+// if `dependent` is still in memory when the signal is aborted.
 aborted(dependent.signal, dependent).then(() => {
-  // Do something when dependent is aborted.

+  // This code runs when `dependent` is aborted.
+  console.log('Dependent resource was aborted.');
 });
 
+// Simulate an event that triggers the abort.
 dependent.on('event', () => {
-  dependent.abort();
