Ask HN: Why isn't Dart more popular?
15 by rlawson | 11 comments on Hacker News.
Played around with a couple of the Google sponsored languages - Go and then Dart. Both exercised different parts of my brain but I feel like Dart has a much lower learning curve for anyone with Java/C# experience. I'm using it with Flutter and it's been great but wonder why it isn't more popular as a general purpose backend language?
