## 🔗 Union Types

```typescript
// Basic unions
status: "active|inactive|pending";
role: "admin|user|guest";

// Mixed type unions
id: "string|number";
value: "string|number|boolean";
```

## 📋 Array Types

```typescript
// Basic arrays
tags: "string[]";
scores: "number[]";

// Optional arrays
categories: "string[]?";

// Array constraints
limitedTags: "string[](1,5)"; // 1-5 items
minItems: "string[](2,)"; // Minimum 2 items
maxItems: "string[](,10)"; // Maximum 10 items

// Combined constraints
usernames: "string(3,20)[](1,100)"; // 1-100 usernames, each 3-20 chars
```

## ❓ Optional Types

```typescript
// Optional fields (can be undefined)
nickname: "string?";
bio: "string(,500)?";
avatar: "url?";

// Optional arrays
tags: "string[]?";
scores: "number[]?";
```

## 🎨 Literal Values

```typescript
// String literals
type: "=user";
version: "=2.0";

// Number literals
apiVersion: "=1";
maxRetries: "=3";

// Boolean literals
isEnabled: "=true";
isLegacy: "=false";

// Complex literals
config: '={"theme":"dark"}';
tags: '=["default","user"]';
```

## 🔍 Custom Patterns

```typescript
// Regex patterns
zipCode: "string(/^\\d{5}(-\\d{4})?$/)";
username: "string(/^[a-zA-Z0-9_]{3,20}$/)";
hexColor: "string(/^#[0-9A-Fa-f]{6}$/)";

// Common patterns
creditCard: "string(/^\\d{4}[\\s-]?\\d{4}[\\s-]?\\d{4}[\\s-]?\\d{4}$/)";
ssn: "string(/^\\d{3}-\\d{2}-\\d{4}$/)";
```
