Recreate Spacewar! as it was developed for the PDP-1 in 1962. Ensure that the design, effects, and features remain true to the original in every detail. Remember, every detail needs to be very identical as the original, including monitor, visual, look and feel, everything. The goal is to replicate so real Spacewar! that every developer believe it "original code running on PDP-1 emulator". Make it functional in a web browser.

GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

Pattern: Sliding Window

    description: "Extract data from TAB_1 to TAB_2"
    command: "sleep 1"
    depends:
      - "Initialize"
  - name: "Update TAB_2"
