I am planning to use an empty <a id="email" href="#"></a> in my html and then using JS to update the href and the content with the proper email a few seconds after the page finished to load.
Would that prevent bots from harvesting the address or is it worthless?

My code works properly, but I am not sure if it’s really efficient against bots.
I have seen options with buttons to make the email appears, or other sort of solutions, but what I want is to have the email shown as a link without any action needed from the user.
