[vm/bytecode] Avoid using map().toList() in bytecode generator Code map((x) => ...).toList() is less efficient compared to an explicit loop. Replacing these code patterns with loops slightly improves bytecode generation speed (dart2js 1271 -> 1188 ms). Also, map with closure consumes more stack space which results in flaky stack overflow errors in kernel service on a test with deeply nested constants.

Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web
Dart has flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.

The easiest way to contribute to Dart is to file issues.
You can also contribute patches, as described in Contributing.
