Comparing walk() vs. no walk() outputs

Printing out lists with map() shows a lot of bracketed text in the console, which can be useful for understanding their structure, but this information is usually not important for communicating with your end users. If you need to print, using walk() prints out lists in a more compact and human-readable way, without all those brackets. walk() is also great for printing out plots without printing anything to the console.
