### Why does Julia use `*` for string concatenation? Why not `+` or something else?

The [main argument](@ref man-concatenation) against `+` is that string concatenation is not
commutative, while `+` is generally used as a commutative operator. While the Julia community
recognizes that other languages use different operators and `*` may be unfamiliar for some
users, it communicates certain algebraic properties.

Note that you can also use `string(...)` to concatenate strings (and other values converted
to strings); similarly, `repeat` can be used instead of `^` to repeat strings. The
[interpolation syntax](@ref string-interpolation) is also useful for constructing strings.
