Developed and maintained by Microsoft, TypeScript is an open-source JavaScript syntactical superset language. Ranked 12th on RedMonk's Programming Language Rankings in 2019, the language is steadily gaining popularity since its 2012 release. Poised to potentially replace JavaScript, TypeScript may become the default language for React, a user interface framework maintained by Facebook and it is already the default language for Google's Angular.

As a superset language, TypeScript allows developers to write code in JavaScript and adds new features to create larger, more complex programs, such as Microsoft's Visual Studio Code. Additionally, the language has: Type annotations, type interface, type erasure, enumerated types, interfaces, generics, namespaces, and more.

If you're interested in learning more about TypeScript, the following list of resources can help you get started.
