deleteChildElements a. Receives a parentElement as a parameter b. Define a child variable as parentElement.lastElementChild c. While the child exists…(use a while loop) d. Use parentElement.removeChild to remove the child in the loop e. Reassign child to parentElement.lastElementChild in the loop f. Return the parentElement function deleteChildElements(parentElement) { let child = parentElement.lastElementChild; while(child) { parentElement.removeChild(child); child = parentElement.lastElementChild; } return parentElement; } The code works but the function deleteChildElements needs to return undefined if an HTML element is not received as a parameter
