This image features the official TypeScript logo: a blue square with bold white letters “TS” in the center. TypeScript is an open-source programming language developed and maintained by Microsoft. It builds on JavaScript by adding optional static typing and powerful developer tools, helping developers write more robust and maintainable code. TypeScript is widely used in modern frontend frameworks such as Angular, React, and Vue, and is especially valued in large codebases for its error detection and IntelliSense support.
