You copy-paste code from a tutorial character by character, triple-check every semicolon, and somehow it still refuses to work. Meanwhile, the tutorial creator is probably running it on some mystical configuration you'll never replicate. Maybe they're on a different Node version. Maybe their environment variables are blessed by ancient gods. Maybe you forgot to restart your server for the 47th time. The real kicker? When you finally give up and write it yourself from scratch, it works immediately. Programming is just gaslighting yourself with tutorials.
