+* Delays the execution of code for a specified number of milliseconds.
+*
+* This function returns a Promise that resolves after the specified delay, allowing you to use it
+* with async/await to pause execution.
+*
+* @param ms - The number of milliseconds to delay.
+* @param options - The options object.
+* @param options.signal - An optional AbortSignal to cancel the delay.
+* @returns A Promise that resolves after the specified delay.
+*
+* @example
+* async function foo() {
+*   console.log('Start');
+*   await delay(1000); // Delays execution for 1 second
+*   console.log('End');
+* }
+*
+* foo();
+*
+* // With AbortSignal
+* const controller = new AbortController();
+* const { signal } = controller;
+*
+* setTimeout(() => controller.abort(), 50); // Will cancel the delay after 50ms
+* try {
+*   await delay(100, { signal });
+*  } catch (error) {
+*   console.error(error); // Will log 'AbortError'
+*  }
