Myles Borins - Keynote
summary
History of JavaScript standards and how Node actually inherits V8 lead to concrete fixes and tradeoffs: Node updates V8 mid-release to get ES features; util.promisify and low‑level promise optimizations reduce allocations and in some measurements async/await outperform callbacks; post‑mortem tooling breaks because promises change unwinding; TC39 needs two engine implementations and about eight months minimum to standardize a feature; an ABI‑stable layer, N‑API, ships experimental in Node 8 to let native modules survive V8 changes.
