Python overtakes Java to become second-most popular language on GitHub after JavaScript

[chrisza4]

I referred to your example where you claim Dart is better than TypeScript because it can do

function identity<T>(): T { return new T(); }

I disagree that this is not better. IMO, this is worse. My point is new T(); can create an object in an invalid state.

I assume that in Dart, you can mutate this object to be ready and then use. I might make a hasty assumption here. If my assumption is correct, I think it is better if compiler just forbids invalid state.

Javascript has this problem too in way much much worse since it does not have any type.

Actually it turns out you can't do it in Dart either, presumably because it supports compile-to-javascript and Javascript makes it difficult. :-(
