Recommendation
Definitions and references are matched together by collapsing whitespace. Using more whitespace in labels might incorrectly indicate that they are of importance. Due to this, it’s recommended to use one space and turn this rule on.

Compatibility
Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of
Node.
This means we try to keep the current release line,
remark-lint-definition-spacing@3
,
compatible with Node.js 12.
