The oc-template-typescript-react has been supporting both Typescript and Javascript for quite a while now, and in general is more mantained. Since this template is the official one, makes sense we merge the other one here, so we can deprecate oc-template-typescript-react and use this one only moving forward.

Ability to init with multiple templates (reference in opencomponents/oc#1331) will allow this template to let you choose between TS flavour or JS depending on your preference.
