> Web development frameworks seem to have a half-life of about 12 months.

Initial realeases of the most popular JS-frameworks:

Angular – 2010

React – 2013

Vue – 2014

Polymer 0.5 - circa 2014 Polymer 1 - 2015 Polymer 2 - 2017 Polymer 3 - 2018 LitElement - 2019

(I'm aware that Polymer insists it isn't a 'framework'. But it is. If their breaking changes cause incompatibilities between components using different Polymer versions, that's what I call a 'framework'.)

*also the ~recent deprecation of Bower

Angular doesn't count as 2010 because they did massive compatibility breaking change to Angular2 such that it was basically a new framework.
