I have a question. Can I create and track any arbitrary custom JavaScript event on my website and then see how many times that specific event was triggered and/or how many unique visitors triggered it?

By "any arbitrary custom event," I mean an action that I define myself. For example, if I have a video on my website, could I use JavaScript to trigger custom events when a visitor reaches certain points of the video, such as: video_25_percent, video_50_percent, etc. And then see within your software how many visitors triggered each of those events?

What I really want to know is that your software allows me to define any custom event based on any action or condition I can detect with JavaScript and then use your software to track, count, and analyze those events.
