I get so tired of the churn claim. Let's look over some stuff
ES6 -- 2015
jQuery -- 2006
React -- 2013
React Native -- 2015
Redux -- 2015
VueJS -- 2013
6to5 (now Babel) -- 2015
Webpack -- 2012
ESLint -- 2013
jslint -- 2002
ExpressJS -- 2010
Lodash -- 2012
UnderscoreJS (basically the same API as Lodash) -- 2009
D3 -- 2011
Blockly -- 2012
Node Red -- 2013?? (I'm not sure when IBM first released the project)
Bootstrap -- 2011
PDF.js -- 2011
WinJS -- 2012
SocketIO -- 2012
ThreeJS -- 2010
dotenv -- 2015
momentJS -- 2011
node-sass -- 2012
Winston -- 2014
yargs -- 2011
Modernizr -- 2009
Jasmine -- 2010
Mocha -- 2011
Jest -- 2015
All of these are at least 5 year old and most are 8-9 years old. Look over the most downloaded npm packages and you'll find this to be generally true for all the top packages.
