How to get href value of anchor tag in JavaScript?

**To get the href value of an anchor tag in JavaScript, you can use the getAttribute() method along with the ‘href’ attribute.**

Let’s break it down step by step. First, you need to select the anchor tag using a querySelector or getElementById method. Once you have the reference to the anchor tag, you can simply call getAttribute(‘href’) on it to retrieve the href value.

“`javascript
const anchorTag = document.querySelector(‘a’);
const hrefValue = anchorTag.getAttribute(‘href’);
