Back to the future of JS: the next features and amazing proposals
summary
Shows concrete syntax and semantics: bind operator adds :: sugar for binding and method extraction; pipeline operator (minimal, smart/top, F# variants) threads values and needs rules for awaits and arrow wrappers; partial application ? token and ... bind specific arguments and turn template strings into callables. Demonstrations include a Meowth component, a sanitize-text pipeline and partial-applied max example; proposals are experimental, have Babel plugins and TC39 issues, and aren’t production-ready yet.
