While we will still have to reevaluate this in the future, we're testing for
versions `>= 15` so this name matches up a bit more precisely.
…slist`.

By default, if no `targets` option is passed, or `browserslist` isn't set in
the `package.json`, `@babel/preset-env` only transpiles to ES2015/ES6.

Since we're only testing Node.js 10+ and we've set the `engines` property to
indicate our intention of only supporting Node.js 10+, I think we can
transpile to a newer target safely.  Not truly important to count bytes in
this package, but this shaves off an unimpressive 8kB (but also a 20%
reduction for this package).

Thanks so much for jumping into this! I pushed a few follow-up commits, but LGTM.

I'll add a note about dropping support for Node.js to the changelog after merging.

This PR didn't introduce it this, but worth noting that this technique of excluding by validator rules by the string-form of their name has broken down once before when subjected to minification since the functions in graphql had been minified themselves. See apollographql/apollo-server#3335.

Because of its role in the ecosystem (in dev tooling) I don't suspect this package or its dependencies will be subject to minification, but just noting. Definitely not asking for a change. 😄

If we don't specify targets here or browserslist in the package.json, this transpiles to ES2015 (ES6) (Source). That's probably fine, but if we're specifying engines at >= 10, I guess we can go ahead and bump the transpilation target. I've done that in 3ecf7de.

I explicitly made a call-out to dropping Node.js from engines. Even if the relatively unenforced engines was the only thing preventing it from working on new versions, I think it's okay for us to take a stance on it 3ecf7de 😄 .

Putting a `const` below the first place it was used was never an acceptable
mechanism for using `const` since it has different dynamics than a `var`.

However, prior to 3ecf7de, we were transpiling `const`
into `var` statements, which are hoisted.
