HTML/JS alerting a specific part of an array and not DOM objects

Hello! I'm trying to alert a specific part of an array I create when i get an element through a tag. Here is the HTML portion

<p id="intro">
  Hello World!
</p>

<p id="info">
  JavaScript on The DOM
</p>

Here is the javascript portion I'm working on 

var elm = document.getElementsByTagName('p');
alert(elm);

I don't know how to create an array of only words and not DOM objects, I also don't know how to specify a specific part of the array to alert.

Any help would be appreciated

To convert the element collection into an array of the text parts you could do something like this:

var elm = document.getElementsByTagName('p');
var words = Array.from(elm).map(p => p.textContent); // convert texts into array
alert(words);

Ok but how would I alert a specific part of an array? Like alert(words[1])?

Ah, I figured it out, thank you.
