}
// Test the function
console.log(reverseString(\"grok\")); // Output: \"korg\"

This function reverses a string efficiently. You can prompt grok-code-fast-1 to generate similar utility functions or optimize existing ones.

Example 2: Simulating an API Call

async function fetchData() {
  try {
    const response = await fetch(\"https://jsonplaceholder.typicode.com/todos/1\");
    if (!response.ok) throw new Error(\"Network response was not ok\");
    const data = await response.json();
    console.log(\"Data:\", data);
  } catch (err) {
    console.error(\"Error fetching data:\", err.message);
  }
}
// Run the function
fetchData();

This example demonstrates a basic API call with error handling. You can use grok-code-fast-1 to generate or debug similar async operations.
