update the lowest supported node version?

[jimmywarting]

The linting and newest version of xo on a old codebase is a little... meh
it clearly have fallen behind in the amount of things it yields about.

One of the thing i settled on was the features we use, and the targeted node.js version.

what do you say about setting it to something more modern like >=12 ?
v12 is ending it's long time support pretty soon now in April

[niftylettuce]

There's no reason why we shouldn't support older versions especially with the help of Babel.

I turned most of those lint errors to warnings via rules override, and for the ones you shared that are node/no-unsupported-features/es-syntax, it is due to the linter not respecting engines having multiple versions specified (obviously it's a bug).

Ref: mysticatea/eslint-plugin-node#315

[jimmywarting]

couldn't we disabled the node/no-unsupported-features/es-syntax rule then if babel takes care of compiling any new es feature we may use then?

[niftylettuce]

I tried to disable that rule but it didn't work for me when I tried. Not sure if you want to go down that rabbit hole.
