1. Reference Types and Literal Types
Today, I started with TypeScript fundamentals and explored how it makes JavaScript development safer and more powerful. Here’s a breakdown of what I covered and some code examples!
Readonly & Optional Properties: These are great for ensuring certain values stay fixed, while optional properties provide flexibility.
Function with Explicit Types: Ensures functions return the correct type, enhancing code predictability.
Typed Arrays: TypeScript enforces type safety in arrays, making methods like .map() safer.
Spread & Rest Operators make handling dynamic data smooth, while destructuring simplifies assignments.
Type Aliases: Creating reusable types for better code structure.
Union Types: Allowing variables to hold multiple types, adding flexibility without sacrificing safety.
Using optional chaining (?) and nullish coalescing (??) operators help keep the code clean and avoid unnecessary null checks.
Starting with TypeScript has been an eye-opener in terms of writing clean, type-safe code! Excited to keep building on this foundation. 💪🔥
