Does Google Dart JavaScript converter support older browsers?

Does the Google Dart JavaScript converter support older开发者_运维问答 browsers or is it only supporting modern browsers?

According to technical overview of its official site :

You will be able to run Dart code in several ways:

1.Translate Dart code to JavaScript that can run in any modern browser: Chrome, Safari 5+, and Firefox 4+ (more browser support coming shortly).

2.Execute Dart code directly in a VM on the server side

3.Use Dartboard to write, modify, and execute small Dart programs within any browser window

There is little chance that the Dart -> JavaScript compiler will support older browsers.

It's supported in no browsers currently. However code in dart can be compiled to JavaScript.
