Notes for class

• Watch beside Functions and closures, which teaches closures in detail and has playgrounds for the counter and the loop.
• The values on screen are computed while the film plays, by running the same functions it shows.
• More: MDN's guide to closures.
• The narration is a synthetic voice (ElevenLabs). Timing follows the narration track, so a recorded voice-over can replace it cue for cue using the transcript.
• With Reduce Motion turned on in the operating system, the film keeps its fades and drops the sliding motion.
• Set in Atkinson Hyperlegible Next and Mono, typefaces the Braille Institute designed for readers with low vision.
