TypeScript Professional Certification

TypeScript is an open-source programming language developed by Microsoft that builds on JavaScript by adding static types. This means you can define variable types, function parameters, and object properties explicitly, which helps catch errors during development rather than at runtime. TypeScript includes features like classes, interfaces, and generics that enhance JavaScript with more robust, maintainable, and scalable code. It compiles down to plain JavaScript, so it can be used in any JavaScript environment. By providing type safety and tooling support, TypeScript aims to improve developer productivity and code quality, especially in large or complex projects.
