Questions & Answers

Q: How do you install Node.js on a local development machine?

To install Node.js, visit the node.js.org website, download the appropriate installer for your operating system, and follow the installation wizard's instructions.

Q: What is the difference between the LTS and current versions of Node.js?

The LTS version receives less frequent updates and is more stable, making it suitable for enterprise applications. The current version is frequently updated with the latest features.
