if statement only runs on second key down

Trying to figure out why the if statement here only runs on the second time a user presses a key down. I'm trying to get it to run starting on the first key down.

Function:

const commentFieldHasText = () => {
    const commentInput = document.querySelector('.add-comment')
    console.log('runs first keypress')

    if (commentInput.value) {
      console.log('only runs second keypress')
    }
  }

Input:

 <input 
   className="add-comment"
   placeholder="Add a public comment" 
   onKeyDown={() => commentFieldHasText()}
 />

Additional Info: onKeyPress doesn't give expected functionality either. onKeyUp does though.

This happens because the keydown and keypress events occur before the actual key is typed.

To fix this, try using the input or keyup events.
