# Advanced TypeScript Types You Should Know

TypeScript's type system is powerful. Let's explore advanced features that can improve your code quality.

## Utility Types

TypeScript provides several utility types:

- Partial - Makes all properties optional
- Required - Makes all properties required
- Pick - Creates a type with selected properties
- Omit - Creates a type without specified properties

## Conditional Types

Conditional types allow you to create types based on conditions:

```typescript
type IsString = T extends string ? true : false
```

## Mapped Types

Transform existing types into new ones:

```typescript
type Readonly = {
readonly [P in keyof T]: T[P]
}
```

## Conclusion

Mastering these advanced types will help you write more robust TypeScript code.
