Turing Prep Chapter 4: Arrays, Hashes, and Nested Collections

June 2019

Index of this series:

So far, we’ve covered some string manipulation and did a few mythical creatures.

You totally don’t have to look through the screencasts in order. I just wanted to call out array/hash manipulation on its own page.

You can also look through the whole playlist.

I’ll add more screencasts for the other files in this directory soon:

$ tree collections
collections
├── README.md 
├── arrays.rb              // done
├── hashes.rb              // coming soon
└── nested_collections.rb  // coming soon

As I’ve mentioned before, I would recommend you try to stay ahead of me in this video. If you get stuck on making a test pass for more than a few minutes, check that spot of the video, then carry on.

This video is so long because I go into excruciating detail on each test, not just showing the given method that works, but showing how I would google for the right answers if I didn’t know them.

Googling is a skill. Get good at it. :)
