Describe the process of defining an Interface object array and effectively utilizing it

I have a sample object array structured like this:

 tasks: todo =  [
      {
        title: string,
        status: number,
        description: string,
        date: Date,
        priority: number
      }
 ]

To handle this, I created an Interface as follows:

interface todo {
  [index: number]:{
    title: string;
    status: number;
    description: string;
    date: Date;
    priority: number;
  }
}

However, when I assign this interface to a variable with the object array, I encounter these errors: Property 'filter' does not exist on type 'todo' and Property 'sort' does not exist on type 'todo'. How can I avoid these errors?

EDIT : Problem Solved:

export interface todo extends Array <{
  title: string;
  status: number;
  description: string;
  date: Date;
  priority: number;
}> {}

Another useful approach is mentioned here:

interface Todo {
  title: string;
  status: number;
  description: string;
  date: Date;
  priority: number;
}

// tasks is an array of Todo
tasks: Todo[] = [...];

Answer №1

Each component in the user interface should represent a specific task or to-do item:

interface TaskItem {
  name: string;
  completed: boolean;
  details: string;
  deadline: Date;
  importanceLevel: number;
}

// tasksList is an array of TaskItem objects
tasksList: TaskItem[] = [...];
