Get and Set Text Content of a DOM Element

function updateElementText(elementId, newText) {
  const element = document.getElementById(elementId);
  if (element) {
    element.textContent = newText;
    return true;
  }
  return false;
}

function getElementText(elementId) {
  const element = document.getElementById(elementId);
  return element ? element.textContent : null;
}

How it works: These utility functions demonstrate how to both read and write the plain text content of an HTML element. `textContent` is generally preferred over `innerText` for performance and consistency, as it retrieves the text content of all elements (including script and style elements) without triggering a reflow, making it ideal for dynamic text updates.
