OOXML is the dominant enterprise document format. Every `.docx` is a ZIP you can unzip — knowing the part layout enables templating, mail-merge, and malware scanning.
WAV is the universal file format for call recordings, IVR prompts, voicemail exports, and PSTN debug captures. Every telephony platform (Twilio, Asterisk, FreeSWITCH) reads and writes WAV-wrapped G.711.
JavaScript is the execution model of the web. The spec is the canonical reference for language semantics — closures, coercion, prototype lookup, module resolution, and async scheduling.
