Question

Will I get replacement of node.js by google Dart, what do you say.

I am pretty much familiar with javascript and jquery
Also I am started using node.js in recent past

What are the advantages and disadvantages of learning Dart
Where could I get code comparison between two.

Answer 1

You can read about Dart at http://www.dartlang.org/docs/getting-started/
Some of the things I found good about Dart are :

1. Limitation is that any performance-wise advantages will be limited to Chrome only.(as,currently only V8 supports) .And for using on other browsers you might need to run some script to convert.
2. good point is that it has native support.
3. A very critical issue with JS is handling concurrency. Dart has “isolates”: these are used for handling concurrency: It might look like a game changer yet to see if it fully working yet.

I would say its too early to say which is better.
