Who can explain what this code does in javascript

Question

document.getElementById("paragraph").textcontent ="Hello, world";

Answer 1

If looks like you're trying to set the textContent of an element which has an id of "paragraph" to "Hello, world".

It will do that as long as:
* You run the JavaScript after the DOM has loaded.

* You have an element which has a textContent property and has an id of "paragraph".

* You change the property you're trying to set from textcontent to textContent.

Answer 2

This selects the Element with the ID "paragraph" from "document" and sets its textcontent to "Hello, world".

After that will somewhere on your Website be shown: Hello, world"

Answer 3

It's basically the text content , (what's written in it ), of the element with id "para".

Like

<div id="para" > Hello world </div>

Hello world is it's text content
