Current React Version — React Technical Interview Questions & Answers

Current React Version

Current React Version

  • Current version means whatever is in that repo’s package.json today — not a blog title from 2019. Open dependencies.react. Say the major. Mention react-dom sits next to it.
  • If they ask ‘latest’, be honest: look it up, don’t invent. Interviewers care that you know where to read the version and that 18+ uses createRoot.
  • Current React Version — output: react 18.3.1 / react-dom 18.3.1. Same major on both packages.

Technical Interview Tip: Where to look + createRoot if 18+.
