On: Swift is like Kotlin

[kybernetikos]

The javascript equivalent would be something like

    Number.prototype.multiply = function({by:multiplier, adding:summand = 0}) {
	return this * multiplier + summand
    }

    console.log((3).multiply({by: 4, adding: 5}))

But of course, javascript APIs are hardly ever written like that. I think it's interesting how the norms of your ecosystem and very small differences in ergonomics in expression make a big difference in behaviour.
