<label for="given-name">Your name:</label>
<input name="given-name" id="given-name" />
<pre id="log"></pre>

The <pre> element’s innerText is updated to the current value of the <input> every time a keyup event is fired.
const logElement = document.getElementById("log");
const inputElement = document.getElementById("given-name");
inputElement.addEventListener("keyup", () => {
logElement.innerText = `Name: ${inputElement.value}`;
});
#log {
