<output id="output"></output>const output = document.getElementById("output");
const filePicker = document.getElementById("file-picker");
filePicker.addEventListener("change", (event) => {
const files = event.target.files;
for (const file of files) {
output.textContent += `${file.webkitRelativePath}\n`;
}
});
