const submitButton = document.getElementById("submitButton");

// select the output div using getElementById
const outputDiv = document.getElementById("outputDiv");

// Add the event handler to the submitButton to get the data from the input field and add it to a textDiv which in turn is added to the output div. 
// This allows you to add multiple data as we did in the last section.
submitButton.addEventListener("click",() => {

    outputDiv.textContent = inputText;
