Imagine the scenario where you have a group of objects, stored in separate variables and you want to get a list of the unique properties from all of the objects.
In the video, we'll look at a couple of different ways of doing this.
The first is to use a JavaScript reduce function. In order to use this, we need to put the objects in to an array and initialise the reduce function as an empty array.
The second method is to use a JavaScript map function in a similar way. However with this approach, we'll need to make sure we call the JavaScript flat function on the end of the call to map to ensure we don't get nested arrays.
