TypeScript
Two days of TypeScript as a typed superset of JavaScript: basic types, generics, decorators, classes and interfaces – for stable software in frontend and backend.
As a specified and typed superset of JavaScript, TypeScript provides not only a language, but also a transpiler that checks the code and translates it to the desired target version of JavaScript. Thus, more stable and durable software can be developed based on JavaScript.

More about TypeScript
TypeScript is a typed superset of JavaScript ("ES202X") that compiles to plain JavaScript. It offers classes, modules, and interfaces to help you build robust components. It is used for large projects and is implemented by Microsoft. Using TypeScript helps in catching errors in the IDE and on transpilation time.Further resources:
History
TypeScript was created by Anders Hejlsberg, Steve Lucco, and Jonathan Turner at Microsoft in 2012 to address the shortcomings of JavaScript in large-scale application development. It aimed to provide static typing and better code organization. It's worth noting that Visual Studio Code, also by Microsoft, is written entirely in TypeScript, showcasing the language's capabilities.
One of the first major projects to adopt TypeScript was Angular, which significantly boosted its popularity and demonstrated its capabilities in building complex web applications.
Today, there's a trend towards rewriting everything written in JavaScript ("ES202X") in TypeScript, due to its improved maintainability and reduced runtime errors. This shift highlights the growing recognition of TypeScript as a superior choice for building robust and scalable applications.
