Post your answer and then try in Ide. If your answers match, kindly reason this, you are great😉 . I couldn't understand the working of this one

robbe’s got it

[Kroppeb]

Is that what the ide gives?

[Shawn]

I haven’t tested but i’m entirely confident that’s the answer lol

[Abinandhan]

@Kroppeb yes

[Abinandhan]

But why could you explain

[Kroppeb]

The reason is that your 5 isn't mutable

[Shawn]

that’s not why

[Kroppeb]

+= is plusAssign() not plus()

[Kroppeb]

mmh not really correct either

[Kroppeb]

x.plus(y) is equivalent with x+y

[Kroppeb]

that's it

[Shawn]

So these examples are predicated on a misunderstanding of lambda returns and how if works as an expression

[Kroppeb]

the if is a statement here

[Shawn]

exactly, it’s a statement and not an expression

[Shawn]

need an else for that

[Shawn]

the IDE is actually hinting at what’s going on — note how it presents the return hint only on the last line

[Abinandhan]

@Kroppeb yup you are right. My bad. Thanks👍

[Kroppeb]

also the var is marked as the value is never changed

[Kroppeb]

but it is not marked with the += as there, the value does change
