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,
micromark-factory-mdx-expression@^2, compatible with Node.js 16.
This package works with micromark version 3 and later.
This package is safe.
