## What I do - Write type-safe TypeScript code - Use generics for reusable types - Create interfaces and type aliases - Implement advanced utility types - Configure tsconfig for projects - Handle strict null checking ## When to use me When building JavaScript applications that need type safety and better tooling. ## Basic Types ```typescript let name: string = "John"; let age: number = 30; let isActive: boolean = true; let numbers: number[] = [1, 2, 3]; let anything: any = "hello"; let unknown: unknown = "world"; function log(): void { } function fail(): never { throw new Error(); } ``` ## Interfaces & Types ```typescript interface User { id: number; name: string; email?: string; readonly createdAt: Date; } type Status = "pending" | "active" | "disabled"; type ID = string | number; ``` ## Functions ```typescript function greet(name: string): string { return `Hello, ${name}`; } const add = (a: number, b: number): number => a + b; function createUser(name: string, age?: number = 18): User { return { name, age }; } ``` ## Generics ```typescript function identity<T>(value: T): T { return value; } interface Box<T> { value: T; } ``` ## Utility Types ```typescript type PartialUser = Partial<User>; type UserPreview = Pick<User, "id" | "name">; type UserWithoutPassword = Omit<User, "password">; ```
