JS Event Tracking Syntax for Key/Value Pair Objects

Can you please write out the syntax for a JS implementation of an event tracking where the event has a property which is a list of objects, such as key/value pairs

Certainly! I can provide you with an example of how to implement event tracking in JavaScript where the event has a property that is a list of objects. This is particularly useful for scenarios like tracking items in a shopping cart or search results. Here's an example based on the Mixpanel JavaScript SDK: LBKSmixpanel.track("Product Added", { "cart": [ { "brand": "Puma", "category": "Jacket", "price": 30 }, { "brand": "Adidas", "category": "Hats", "price": 15 } ] });LBKSIn this example, we're tracking an event called "Product Added" with a property called "cart" that contains a list of objects. Each object in the list represents an item with properties like "brand", "category", and "price".It's important to note that Mixpanel has some limitations on list of objects properties: 1. The property is limited to 8KB for event properties. 2. Each object can have a maximum of 255 keys. 3. By default, only the first 5 objects within the list will be parsed in the Mixpanel UI.For more details on list of objects property support, you can refer to the Mixpanel documentation on List of Objects Property Support.
