C# vs Dart: differences

Developers describe C# as "Simple, general-purpose, object-oriented programming language for the .NET platform". C# (pronounced "See Sharp") is a simple, modern, object-oriented, and type-safe programming language. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers. On the other hand, Dart is detailed as "A new web programming language with libraries, a virtual machine, and tools". Dart is a cohesive, scalable platform for building apps that run on the web (where you can use Polymer) or on servers (such as with Google Cloud Platform). Use the Dart language, libraries, and tools to write anything from simple scripts to full-featured apps.
C# and Dart can be categorized as "Languages" tools.
"Cool syntax" is the top reason why over 280 developers like C#, while over 19 developers mention "Backed by Google" as the leading cause for choosing Dart.
Intuit, Stack Exchange, and OpenTable are some of the popular companies that use C#, whereas Dart is used by Google, Blossom, and WorkTrail. C# has a broader approval, being mentioned in 697 company stacks & 1163 developers stacks; compared to Dart, which is listed in 19 company stacks and 78 developer stacks.
