Collections of data

In this session, we learn basic manipulations of collections of data: how to walk through every element of a collection using a for loop, how to select elements from a collection with the filter function, and how to transform every element of a collection using the map function.

Everything we cover is summarized in a Pluto notebook you can view here. The notebook includes a couple of more challenging self tests you can try out. To run the notebook interactively, use the button at the top right of the page
