javascript - 无法为访问函数创建 javaScript 算法

Question

我的应用程序中有一些选项卡，例如报告、任务等...用户也有不同的权限，如 reports.add、tasks.delete。我需要创建函数来检查允许用户做什么。

// for example array with all current user permissions
// this permissions mean user is allowed to do everything with tasks
// add and edit reports, but not allowed to to delete it

const permissions = ['reports.add', 'reports.edit', 'tasks'];

const isAllowed = (condition) => {
   return permissions.some((permission) => {
            // here is problem, I can't create algorithm
       });
};


// When user clicks delete report button 
// I expect to use this function like this 

if (isAllowed('reports.delete')) {
    deleteReport()
}

如果 condition 以 permission 开头，您可以在 permissions 中搜索。

const
    permissions = ['reports.add', 'reports.edit', 'tasks'],
    isAllowed = condition => permissions.some(permission => condition.startsWith(permission));

console.log(isAllowed('reports.add')); //  true
console.log(isAllowed('tasks.edit'));  //  true
console.log(isAllowed('tasks'));       //  true
console.log(isAllowed('task'));        // false
