我想在此处按子句顺序使用SUM(Quantity)-

import React from "react";
import { NavLink } from "react-router-dom";
import styled from "styled-components";

const NavStyle = styled.div`
  margin: 10px;
  a {
    color: red;
  }
`;

const Navigation = () => {
  return (
    <div>
      <NavStyle>
        <NavLink to="/">Home</NavLink>
      </NavStyle>
      <NavLink to="/about">About</NavLink>
      <NavLink to="/contact">Contact</NavLink>
    </div>
  );
};

export default Navigation;

我该如何实现?

没有什么可以阻止您在此处使用.Sum()。这是一个工作示例:
