let is like writing your name with a pencil or washable marker; it can be changed or erased later.

const is like writing it in permanent marker. Once you write it it has to stay the same forever.

const modalMarkup = `
`; // 2. Append the markup string to the end of the document body document.body.insertAdjacentHTML('beforeend', modalMarkup);
