Difference between TypeScript and Dart language

TypeScript: It is an open-source pure object-oriented programming and compiled language which is developed and maintained by Microsoft. It has been influenced by JavaScript, Java, C#. It is C-style syntax and it can optionally trans-compile into JavaScript and it used to develop web and mobile applications. First release of TypeScript was in October 2012. It is a typed superset of JavaScript like CoffeeScript means it is a JavaScript with some additional features.

Dart: It is an open-source, general-purpose class-based, an object-oriented programming language which is developed and maintained by Google. Dart is a typed superset of JavaScript. It is a full scripting language that compiles to plain JavaScript and it is used to build JavaScript applications for both client-side and server-side execution. It has been influenced by C# language, Erlang, JavaScript and Smalltalk. The first release of Dart was in November 2013. It is a full scripting language, that’s why called Google replacement of JavaScript.

Companies that use Dart are Google, Blossom, and Workiva, etc.
