TypeScript Utility Types

TypeScript gives tools to transform types. ## Base type ```ts type User = { id: number; name: string; email: string; }; ``` ## Partial ```ts type UserDraft = Partial<User>; ``` ## Required ```ts type FullUser = Required<UserDraft>; ``` ## Pick ```ts type UserPreview = Pick<User, "id" | "name">; ``` ## Omit ```ts type UserNoEmail = Omit<User, "email">; ``` ## Record ```ts type Scores = Record<string, number>; ``` ## Graph ```mermaid flowchart TD A[User] --> B[Partial] A --> C[Pick] A --> D[Omit] ``` ## Remember - Utility types reshape types - Avoid rewriting similar types
