What will be the result of following code executio | CodeGalaxy.io

What will be the result of following code execution?

object Main extends App {
  def quiz = {
    val result = 5
       + 6
  }
  println(quiz)
}

Explanation

The function will be interpreted as following:


  def quiz = {
    val result = 5;
    + 6
  }

The result will be last line: +6

One issue with Scala’s semicolon convention is how to write expressions that span several lines. For instance
```
someLongExpression
+ someOtherExpression
```
would be interpreted as two expressions:
```
someLongExpression;
+ someOtherExpression
```
To overcome this problem you could write the multi-line expression in parentheses, because semicolons are never inserted inside (...):
```
(someLongExpression
+ someOtherExpression)
```

Shouldn't be there also a warning about local variable `result` not being used?
