" summary

Claim: prioritize optimize for correctness over keystroke speed by minimizing complexity, eliminating shared mutable state, and preferring pure functions. Demonstrations use factorial examples to show bugs from leaked state, show map/filter/forEach and const plus Object.assign for immutable updates, warn that Object.freeze is misleading, mention tail call optimization isn’t available in browsers, and suggest using Immutable.js or web workers for safe parallelism; 700 people attended.
