TypeScript is an extended version of JavaScript with added type syntax for better type checking and auto-completion during editing. While TypeScript code must be converted to JavaScript for execution, modern runtimes like Node.js and Deno can run TypeScript directly. Transpiling refers to the conversion process, which can be controlled via the tsconfig.json configuration file. TypeScript supports bundling for web applications and integrates well with various tools and IDEs, including Visual Studio Code. Libraries are often published with type declaration files to enhance compatibility with both JavaScript and TypeScript projects.
