adding text to an existing text element in javascript via DOM

I am trying to figure how to add text to a p tag or h1 tag that already has a text node.

For example:

var t = document.getElementById("p").textContent;
var y = document.createTextNode("This just got added");

t.appendChild(y);
<p id="p">This is some text</p>

The reason that appendChild is not a function is because you're executing it on the textContent of your p element.

You instead just need to select the paragraph itself, and then append your new text node to that:

var paragraph = document.getElementById("p");
var text = document.createTextNode("This just got added");

paragraph.appendChild(text);
<p id="p">This is some text</p>
