The simplicity of the language and the debugger.

Dart is easy to pick up. If you are coming from a JavaScript background, then you will find many concepts familiar and easy to use. The language allows you to work without using types or you can use types just like TypeScript. If you are familiar with async/await in JavaScript then congratulations, you are right at home. The tooling around Dart is much better compared to even TypeScript. To me, Dart is the best language that Google has created after Go Lang. If you haven't used the language, then try once, and you'll not look back. Thanks.

The languages and the the hierarchy of languages itself are very easy to understad. More simple than the other languanges that i have ever used. Its very helpful for begineer to use
