/**
* A custom React hook that invokes a specified effect function on every update after the initial render.
* This hook is designed to avoid executing the effect on the first render, while still allowing it to execute on subsequent updates.
*
* @param fn - The effect function to be invoked on update after the initial render.
* @param dependencies - The dependencies to be used by the `useEffect` hook that triggers the effect function.
*
* @example
* ```tsx
* import { useState }
* function MyComponent() {
* const [count, setCount] = useState(0);
*
* useDidUpdate(() => {
* console.log('Component updated!');
* }, [count]);
*
* return (
* <div>
* <p>Count: {count}</p>
* <button onClick={() => setCount(count + 1)}>Increment</button>
* </div>
* );
* }
* ```
