A modern programming language that makes developers happier.

kotlinlang

`fun isFavorite(otherIceCream: IceCream) = iceCream == otherIceCream`

What is going on in this syntax? We have one equality operator and another is assignment.

Yeah I'm not a huge fan of the "fun(...) = " syntax either, you could read this as:
```fun isFavorite(other: IceCream) {
    return iceCream == otherIceCream
}
```

Some languages like Dart use `=&gt;` in this case which makes it a bit clearer imho. Would look like this in your example:
```fun isFavorite(otherIceCream: IceCream) =&gt; 
        iceCream == otherIceCream```

`iceCream == otherIceCream`

Does this mean return true if they are equal or false otherwise.
