Now, there are modern alternatives for loading modules as scripts in HTML documents. Starting with React 19, React will no longer produce UMD builds to reduce the complexity of its testing and release process. diff --git a/src/content/community/team.md b/src/content/community/team.md index 407448f48..b11925407 100644 --- a/src/content/community/team.md +++ b/src/content/community/team.md @@ -38,7 +38,7 @@ Current members of the React team are listed in alphabetical order below.
