JavaScript

var assert = require('assert');
var nvu = require('node-version-use');

var isWindows = process.platform === 'win32' || /^(msys|cygwin)$/.test(process.env.OSTYPE);
var NODE = isWindows ? 'node.exe' : 'node';

// results is an array per-version of form {version, error, result}

});

// results is an array per-version of form {version, error, result}
