Engineering JavaScript for Web3
summary
NEAR adds a JavaScript smart‑contract path that compiles JS to WASM/base64 and runs in a QuickJS JS VM deployed as a contract; tooling shown includes near-sdk-js, near-cli/near-js, near-api.js and a Gitpod quickstart. Demo builds a greeting and a coin‑flip game using a cross‑contract call to a random hub (returns 0/1), deploys via Dev‑deploy (grants 200 testnet tokens), uses 300 Tgas for calls, charges ~0.1 NEAR first‑time storage, and works live on testnet with a 4.19 MB initial upload limit.
