React Modernization
React Modernization is an code AI skill with a core value of Upgrade React applications to latest versions, migrate from class components to hooks, and adopt concurrent features. It
helps developers solve real-world problems in the code domain, boosting
efficiency, automating repetitive tasks, and optimizing workflows.
Upgrade React applications to latest versions, migrate from class components to hooks, and adopt concurrent features. Use when modernizing React codebases, migrating to React Hooks, or upgrading to...
