# Closure

*Define and chain Closures with Inputs and Outputs*

## Examples

**No Scoped State**

```swift

let noStateCount = Closure { text in

  String(repeating: text, count: 4)

}

.then { string in

  Int(string) ?? 0

}

XCTAssertEqual(noStateCount.method("5"), 5555)

XCTAssertEqual(noStateCount.method("5"), 5555)

XCTAssertEqual(noStateCount.method("5"), 5555)

```

**Scoped State**

```swift

let stateCount: Closure = Closure {

  var count = 1

  

  return { text in

    defer {

      count += 1

    }

    

    return String(repeating: text, count: count)

  }

}

.then { string in

  Int(string) ?? 0

}

XCTAssertEqual(stateCount.method("5"), 5)

XCTAssertEqual(stateCount.method("5"), 55)

XCTAssertEqual(stateCount.method("5"), 555)

```
