This is the nineteenth video in Part 3 of the Performance-Aware Programming series. Please see the Table of Contents to quickly navigate through the rest of the course as it is updated weekly. The listings referenced in the video (listings 144, 145, 146 and 147) are available on the github.
Separately, I am told that Substack now properly includes captions on videos everywhere, so I will not be pasting in the captions here as normal. If anyone still needs caption data for some reason, please let me know in the comments.
