How did the void(0) thing work in links? I remember being frustrated by it when I couldn't see where the link would take me, but never understood what was going

  these links have an onclick handler. If the handler goes missing or fails, this construct will prevent the link from doing what it usually would. But using a button is better in such cases...

Back then, you'd use it with the `href` attribute to prevent the link from going anywhere (it would return `undefined`), then call a function with the `onclick` attribute. E.g. <a href="javascript:void(0)" onclick="clickHandler()">Click me</a>

  Basically it defers to a javascript function instead of using the web's normal way of linking. An example of such a link would be: <a href="javascript:void(0)" onclick="dostuff()">Click me</a> href="javascript:void(0)" basically tells the browser to do nothing when a link is clicked. It's like returning false from an event listener. onclick="dostuff()" will then listen for clicks and call the `dostuff` function to update the page or load a new one. Nowadays it's considered bad practice and to be honest it wasn't exactly good practice in those days but it was very commonly used.
