Possible, and also shaped with recent language experiences. My first languages were JavaScript and C++ pretty much simultaneously. In both I'd write a max function with a ternary operator. It signals to me — in the same way as if/else — that no outcome is expected to be more usual or typical than the other, and that no path is more notable or interesting that the other.

The control flow isn't confusing either way, and some language linters will insist against if/else in this example, but I see the if/else approach with slightly more clarity. In general, though, I'm a big proponent of early return.
