How to Change Element Text in HTML Using <script>

Are you looking to update the text of an HTML element using JavaScript? Maybe you want to change the content of a paragraph tag from "Success" to something like "IDK MAN".

The '.card-text' selector targets elements with the class card-text.

Now that we have our element stored in the variable tag_p, we can easily change its text content. We can do this using the textContent property. Here’s the code to change the text:
