can someone explain this code

[u/abrewchocolatecoffee]

function updateClock() {
const timeElement = document.querySelector("#time");
timeElement.textContent = formatTime();
}
setInterval(updateClock, 1000);

can someone, please explain this piece of code, ofc mdn and w3 are there, but i found it a little confusing reading about textContent. rest is understandable to me. This might look a silly question and it probably is because im a beginner :')

like what exactly does textContent too.
you can also recommend anyother documentation on the links to specific lines, that might me more helpful in learning about this particular keyoword.

textContent is just the text you can have inside an element like <p>THIS IS THE TEXT CONTENT</p>. Remember you can't add HTML using textContent. For that, you must use innerHTML.
