Working with React Native CI pipelines?
Instead of pushing commits just to debug GitHub Actions workflows, you can run them locally.
I built an open-source Docker setup called Expo-RN-Runner that lets you test React Native CI locally using act CLI.

Tuples Lock Down Array Length and Position Types
Tuples enforce exact array positions and types, fixed length, position-specific safety.

Index Signatures Let Objects Accept Any Key
Index signatures enable dynamic keys with type safety -perfect for dictionaries and lookup tables.

Use Generics to Replace Repetitive Type Definitions
One generic type replaces dozens of definitions same safety, way less code.

Interface extends vs Intersection Types
extends and & look similar but handle conflicts differently extends errors early, & merges types.

readonly Properties Aren't Actually Immutable
readonly prevents reassignment but doesn't freeze nested properties mutation still happens.

Optional Properties Work Better with Destructuring Defaults
Use destructuring defaults with optional properties cleaner code, no undefined checks needed.

Understanding TypeScript's void Return Type
void doesn't mean "no return" it means "ignore the return value." That's why forEach and push work together.

This Valentine’s Day, I wrote about the most dramatic relationship in a developer’s life — Git ❤️
Commits, conflicts, rebases, and emotional damage.

Union Types Over Function Overloads
Replace function overloads with union types for cleaner, more flexible code.

Optional Parameters in Callbacks - The Gotcha
Don't use optional parameters in callback types, always pass the arguments or your code breaks at runtime.

Exactly, Overloads define the public API surface. The implementation is just an internal detail. TypeScript enforces the contract at compile JavaScript only sees one function at runtime.
Why Your Function Overload Implementation Isn't Visible?
Function overload implementations are invisible from the outside only the overload signatures matter.

Generic Functions Make Types Flow Automatically
Generics automatically infer types based on what you pass in no manual type specifications needed.

The TypeScript Compiler (tsc)
tsc compiles TypeScript to JavaScript. Type annotations get stripped away they only exist during development. Your runtime code stays clean. No overhead, just safety.
tsc hello.ts -> it creates hello.js
