Documentation of a langauge, framework, or tool is the information that describes its functionality. For this part of the practice tasks, you're going to practice digging into documentation and other reference material.

On a blank sheet of paper, create a diagram that shows how you understand iteration working. Be detailed and get creative! This should not be the simple table that we used during the lesson. When you're done, take a photo of your diagram and send it to Rachel and Tim on Slack. (If you're feeling extra fancy, feel free to create your diagram using software instead of pencil and paper)
-
Create a list below of three real-life situations where iteration is used. For each situation, explain why it would be an example of iteration.
-
Doing inventory for a business. Every week you are updating your inventory of products.
-
Creating a recipe. You may change the amounts and ingredients many times before coming to a final recipe.
-
Grades. Grades are continually changed and updated throughout a course.
-
Create a list below of three programming situations where iteration would be used. For each situation, explain why it would be an example of iteration.
-
A game that is constantly updating light. It would have to constantly be updating due to shadows and brightness of day.
-
A website with a live clock on it. While the website page is being viewed the time is being updated.
-
A production assembly line program. Telling machines what to do to build something and repeat.
Ryan, nice job with this task. I encourage you to provide examples whenever possible, as this will help you gain a mastery of these concepts. Also remember for iteration, we always start with a collection, so for your inventory example, the inventory is the collection, and for each item you will update it's status.
