Remove Attribute with JavaScript

https://developer.mozilla.org/en-US/docs/Web/API/Element/removeAttribute

removeAttribute(attrName)

document.getElementById("div1").removeAttribute("align");

Here’s how I used it personally on a website:

let subMenuLinks = document.querySelectorAll('.sub-menu li a');

for (i = 0; i < subMenuLinks.length; i++) {
    console.log(subMenuLinks[i]);
    subMenuLinks[i].removeAttribute('href');
}
