Recommendation
GitHub flavored markdown (GFM) specifies that two tildes should be used,
but github.com
allows one tilde everywhere.
It’s recommended to use two tildes.
Fix
remark-stringify
with
remark-gfm
formats all strikethrough with two tildes.

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-strikethrough-marker@2
,
compatible with Node.js 12.
