[docs, babel-jest] Getting started: "regenerator-runtime is not explicitly required"

[twisty]

The example commands to install babel-jest (in “Additional Configuration > Using Babel”) all include installing the regenerator-runtime package.

Then, there is a note that reads:

Note: Explicitly installing regenerator-runtime is not needed if you use npm 3 or 4 or Yarn

Does this mean regenerator-runtime is required on npm@<3||>4, or this documentation outdated?

If this is the case, maybe we should not include installing regenerator-runtime in the yarn add example, and change the note to mandate installing regenerator-runtime for the minority still using npm version 1.x or 2.x?

[twisty]

Are we asking users to superfluously add regenerator-runtime dependency to their projects, when this is only required for users running outdated versions of npm?

I'm happy to rewrite the doc and send a PR if this is the case.

I don't have the capacity to dig into the technical facts, maybe someone reading this can shed some light?

Hey @twisty, thanks for working to improve this

Check out the discussion here I think that's where this originated

[twisty]

@rickhanlonii Will check that out, thanks.

Is this still an issue .. and if so .. Can i take this up?
and what is the verdict on Babel section of the docs regarding regenerator-runtime?

[mrazauskas]

The documentation related to regenerator-runtime was removed in #7016. Most probably this is not an issue any more.

[SimenB]

Yep, this is no longer relevant. Thanks for the offer, though! #7595 removed it from Jest
