I think what he means is why not use ++ in the click handler. We don't need a function to increment something.

Standard HTML, onclick="var++"

No, I think he's referring to the fact that the function increment is called by interpreting the string "increment".

you can do exactly that, they just wanted to showcase the methods option. often you would switch true to false doing:

`@click="isSomething = !isSomething"`

Exactly this. Template directives support a lot of JS functionality (while not encouraging it, like JSX does). That said, except in rare, extremely simple cases I still prefer wrapping that logic in a computed property or method, as it will inevitably grow more complex later.
