When I start a brand-new CRA typescript project, I seem to get stuck with an ancient version of Jest:
create-react-app my-app --scripts-version=react-scripts-ts
cd my-app
yarn test -v
v20.0.4
... but the same thing for a javascript project (e.g. without --scripts-version=react-scripts-ts) gets Jest 23 (the latest as of this writing).
1) what might I be doing wrong?
2) is there something I can do later to get a correctly-configured jest 23 for typescript?
