NodeJS is great because it's just JavaScript, and you can use JavaScript everywhere. I'm saying this as someone who's been doing web development since the 1990

NodeJS is great because it's just JavaScript, and you can use JavaScript everywhere. I'm saying this as someone who's been doing web development since the 1990s and have used at least a dozen of the most popular frameworks over the years. Other than NodeJS consider Rails, as it is chock full of best practices in terms of security, testing and code organization. IMO tools like Django or anything from the Java world lag far behind in terms of features and tend to carry too much baggage from their past. Others will disagree with some of this, which is fine, but YMMV.
