Learn how to build and execute your first practical generic function in TypeScript! In this step-by-step hands-on tutorial, we dive into Module 3 by creating `01-generics.ts`, writing reusable container functions (`wrapInArray`, `wrapInObject`), resolving object return syntax errors, executing code with `npx tsx`, and configuring custom npm scripts in `package.json`.
Whether you’re developing full-stack web applications or setting up backend Node.js APIs, knowing how to write generic function wrappers and execute TS code efficiently is an essential daily developer workflow.
📌 What You’ll Learn:
• Setting up Module 3 workspace & creating `01-generics.ts`
• Writing type-safe generic container functions in TypeScript
• Resolving common object return syntax & type errors in VS Code
• Running TypeScript files instantly in terminal using `npx tsx`
• Configuring `package.json` build scripts for efficient execution
