const fileInput = document.querySelector("input[type=file]");
const output = document.querySelector(".output");
fileInput.addEventListener("change", () => {
const fileList = fileInput.files;
if (fileList.length > 0) {
const file = fileList.item(0);
output.textContent = `You selected: ${file.name}`;
}
});
