const curriedAdd = curry((a, b, c) => a + b + c)

curriedAdd()        // returns curry((a, b, c) => a + b + c)
curriedAdd(3)       // returns curry((b, c) => 3 + b + c)
curriedAdd(3)(4)    // returns curry((c) => 3 + 4 + c)
curriedAdd(3)(4)(5) // returns 12
curriedAdd(3, 4)(5) // returns 12
curriedAdd(3)(4, 5) // returns 12
curriedAdd(3, 4, 5) // returns 12
