删除js重复代码

很多时候虽然是同一个功能，但由于一两个不同点，让你不得不写两个几乎相同的函数。

 

function showDeveloperList(developers) {
  developers.forEach((developer) => {
    const expectedSalary = developer.calculateExpectedSalary();
    const experience = developer.getExperience();
    const githubLink = developer.getGithubLink();
    const data = {
      expectedSalary,
      experience,
      githubLink
    };

    render(data);
  });
}

function showManagerList(managers) {
  managers.forEach((manager) => {
    const expectedSalary = manager.calculateExpectedSalary();
    const experience = manager.getExperience();
    const portfolio = manager.getMBAProjects();
    const data = {
      expectedSalary,
      experience,
      portfolio
    };

    render(data);
  });
}

　　

function showEmployeeList(employees) {
  employees.forEach(employee => {
    const expectedSalary = employee.calculateExpectedSalary();
    const experience = employee.getExperience();
    const data = {
      expectedSalary,
      experience,
    };

    switch(employee.type) {
      case 'develop':
        data.githubLink = employee.getGithubLink();
        break
      case 'manager':
        data.portfolio = employee.getMBAProjects();
        break
    }
    render(data);
  })
}
