Task Manager Class

Build a task management system that organizes and filters tasks efficiently.

Requirements

Implement a TaskManager class that:

1. Stores a collection of tasks, where each task has:

   • A title (string)
   • A priority (number: 1=low, 2=medium, 3=high)
   • A status (string: "pending", "in-progress", or "completed")
   • A due date (Date object)

2. Provides methods to:

   • Add a task to the collection
   • Get all tasks with a specific status
   • Get all high-priority tasks (priority === 3)
   • Get tasks due within the next N days
   • Mark a task as completed by title

3. The class should:

   • Automatically bind all methods so they can be called with any context
   • Use a parent BaseManager class that provides a log method for tracking operations
   • Use efficient filtering with guard conditions

API

class BaseManager
  log: (message) ->
    console.log "[#{new Date().toISOString()}] #{message}"

class TaskManager extends BaseManager
  constructor: () ->

  addTask: (title, priority, status, dueDate) =>

  getTasksByStatus: (status) =>

  getHighPriorityTasks: () =>

  getTasksDueSoon: (days) =>

  completeTask: (title) =>

module.exports = { TaskManager, BaseManager }

Test Cases

• Creating a TaskManager and adding a task with title "Write tests", priority 3, status "pending", due date 2 days from now stores the task correctly @test

• Calling getTasksByStatus("pending") returns only tasks with "pending" status @test

• Calling getHighPriorityTasks() returns only tasks where priority equals 3 @test

• Calling getTasksDueSoon(7) returns tasks with due dates within the next 7 days from today @test

• Calling completeTask("Write tests") changes that task's status to "completed" @test

• Methods remain bound when extracted from the instance and called separately @test

• The log method from BaseManager is accessible via super and logs operations @test
