Check for current Node Version

Question

I need to programmatically access the current node version running in a library I am writing. Can\'t seem to find this in the docs.

If you need to only check for the major version, you can use this quick-and-dirty snippet:

const NODE_MAJOR_VERSION = process.versions.node.split('.')[0];
if (NODE_MAJOR_VERSION < 12) {
  throw new Error('Requires Node 12 (or higher)');
}

Notes:

• process.versions.node is easier to work with than process.version, as you do not have to worry about whether the version starts with a leading v.
• If you still need to distinguish between ancient versions (e.g., 0.10 and 0.12), this will not work, as they will all be considered version "0".
