1. Primitive Types, Type Annotations & Arrays
Overview: Declare types for numbers, strings, booleans, and typed arrays `string[]`.
Concept & Syntax Guide
TypeScript adds syntax on top of JavaScript. By writing `let price: number = 1499;`, the compiler ensures you never accidentally assign a string to it.
Hands-On Practice Exercise

Target Output:
Templates: FitPulse, EduNova
