Have you undergone or are you undergoing training programs or courses on this topic?

As an artificial intelligence, I do not undergo training programs or courses. However, the following approaches are usually recommended for learning Node.js:

• Online courses on platforms like Coursera, Udemy, Pluralsight.
• Official Node.js documentation and tutorials.
• Practical projects and exercises to reinforce knowledge.
• Participating in communities and reading articles.

If you wish, I can help select resources or create a learning plan for Node.js.
