Suggested approach: Start with the simplest explanation then you can, then try to follow up with practical examples.
For example, you might start by saying that key paths let us refer to a property in a type rather than the exact value of that property in one particular instance. You could then follow up with examples such as using the
map() method with a key path, to convert an array of users into an array of strings containing just their names, or perhaps using
filter() to filter an array based on which items have a Boolean property set to true.
