Which JavaScript value should I use for “href”?

[Brianhip]

Hello,

The following are two methods of building a link that has the sole purpose of running JavaScript code. Which is better in terms of functionality, page load speed, validation purposes, etc.?

function myJsFunc() {
    alert("myJsFunc");
}

<a href="#" onclick="myJsFunc();">Run JavaScript Code</a>

or

function myJsFunc() {
    alert("myJsFunc");
}

 <a href="javascript:void(0)" onclick="myJsFunc();">Run JavaScript Code</a>

I would honestly suggest neither. I would use a stylized <button></button> for that behavior.

We usually use the first option because using "#" in href can scroll the page to the top. so by considering this, we use javascript:void(0).
also, the better solution is using buttons because they created for this purpose.
