I've had Copilot teach/tell me about things I didn't know I needed to be considering.

I was writing a parser for URL query strings (?these=things&key=value) and at one point Copilot suggested

  return [decodeURIComponent(key), decodeURIComponent(value)];

and until I saw that I didn't even know that percent encoded text in URLs is something I needed to be thinking about.
