ES6 is good, TypeScript is gaining ground, people are moving away from Flow.
Angular is dead? Most don't even want to touch it again ( Great ). Ember hasn't moved a bit in three years with a declining of interest. I am also surprised no one is using preact. The Choice is now either React or Vue.js, I think Vue.js 3.0 will continue to move vue forward.
Given the amount of hype with GraphQL, I am surprised only 20% are actually using it. And nearly 50% are using Redux!
Backend is dominated by Express only, and Testing framework doesn't have a clear winner either.
And my biggest surprise is how Javascript turned from one of the most hated programming language ( besides PHP ? ) into being acceptable and loved.
I really wish other languages communities do a similar survey, Python, PHP, Ruby, Java, Rust etc... It will be interesting to see the trend and big picture.
