Mixpanel uses asynchronous JavaScript to avoid impacting website performance, which can lead to issues when trying to track click events because the non-blocking nature of the code allows the page to change before the tracking call resolves. To address this, instead of adding a track event directly to a click handler, Mixpanel recommends using the mixpanel.track_links function, which handles the potential problem of the page changing before an event is tracked. This function should be invoked in document.ready or after the link to be tracked has been processed, ensuring that the click event is properly recorded. The mixpanel.track_links function takes a CSS-style selector for the link, the event name, and optionally, additional properties, as detailed in the full documentation.
