O ekonomiji upravljanja paketima — Esejska verzija C J Silverio govora sa JSConfEU ▶️ (pogledajte ako imate slobodnih 35 minuta). Ona je svrgnuta sa mesta CTO u npm, Inc. -u prošle godine ali se vratila sa istorijom ekosistema JavaScript paketa, diskusijom o tome ko ga zaista “poseduje”, i preporukom za novi put usmeren ka Entropicu, novom, agnostičkom registru paketa.  C J SILVERIO Nekoliko novih JS funkcija i upoznavanje sa “opcionim ulančavanjem” sada u fazi 2 — Nove JavaScript funkcije prolaze kroz različite faze pre nego što postanu zvanične i ovaj ?.  operator, koji vam omogućava opciono ulančavanje svojstva ili poziva funkcije, je napredovao.

GitHub je dodao podršku za upotrebu GitHub skladišta kao 'šablona skladišta'.  Označite skladište kao šablon a zatim će taj šablon biti upotrebljen za brzo generisanje novih skladišta. Može biti korisno za šablonske projekte. Na ovonedeljnom WWDC događaju, Apple otkrio je novi proizvod Mac Pro koji je “zver” od mašine.
