Why use document.getElementByTagName("span") instead of document.getElementsByClassName("last_name")?
In the selecting elements code challenge, the correct answer is document.getElementByTagName("span"). Why we use it instead of document.getElementsByClassName("last_name")?
You can use either way - I tested it. When selecting by class name, you'll get an array of elements just like when selecting by tag name.
// by tag name var lastName = document.getElementsByTagName("span"); // by class name var lastName = document.getElementsByClassName("last_name");
Thanks, i didn't include the array, that's why it did not pass the challenge
