Unlock the full power of the TypeScript Compiler (TSC)! In this tutorial, we move from basic compilation to advanced project configuration. Learn how TypeScript “predicts” your types, how to use Watch Mode for faster development, and what those complex `tsconfig.json` settings actually do for your code quality.
**In this video, you will learn:**
* How Type Prediction works during variable declaration.
* Essential CLI commands: `npx tsc`, `tsc –watch`, and `tsc –init`.
* Understanding the project structure: Root, Source, and Output folders.
* Deep dive into Compiler Options: `sourceMap`, `declaration`, and `strict` checks.
* How to catch bugs automatically with `noUnusedLocals` and `noUnusedParameters`.
