Solution

The statement is written in JavaScript, specifically using React Hooks. The useEffect hook is used to perform side effects in function components.

Here's a step-by-step breakdown of the code:

  1. useEffect is a function that takes two arguments: a function and an array.

  2. The function () => { console.log('hello') } is the first argument to useEffect. This function will be executed after the render is committed to the screen.

  3. The array [state1, state2] is the second argument to useEffect. This is the dependency array.

The true statement for the above code is:

"The console will log 'hello' every time either state1 or state2 changes. If neither state1 nor state2 changes between renders, the function will not be executed."
