Task List [Part 3] - Persist To Local Storage

This video tutorial demonstrates how to use JavaScript to persist tasks in local storage, ensuring they remain after page reloads. It covers storing, loading, deleting, and clearing tasks, with a focus on manipulating the DOM and using JSON for data handling. The tutorial provides a practical example of managing tasks in a web application, highlighting key JavaScript functions and local storage operations.

What is the primary purpose of using local storage in this JavaScript application?

• To persist data across page reloads

• To store data temporarily during a session

• To secure sensitive user information

• To enhance the performance of the application

Which function is responsible for adding tasks to local storage?

• initializeTaskArray

• parseTaskData

• storeTaskInLocalStorage

• addTaskToDOM

What method is used to convert tasks into a format suitable for local storage?

• JSON.stringify

• localStorage.getItem

• JSON.parse

• localStorage.setItem

How does the application ensure tasks are displayed after a page reload?

• By storing tasks in cookies

• By using session storage

• By calling a function on DOMContentLoaded

• By using a server-side database

What is the role of the 'get tasks' function in the application?

• To retrieve and display tasks from local storage

• To delete tasks from the UI

• To clear all tasks from local storage

• To add new tasks to the DOM

What challenge is faced when deleting tasks from local storage?

• Tasks do not have unique identifiers

• Local storage cannot be modified

• Tasks are stored in an encrypted format

• Local storage is read-only

Which method is used to remove a specific task from the local storage array?

• Array.pop

• Array.splice

• Array.slice

• Array.shift

What happens when the 'clear tasks' function is executed?

• All tasks are removed from the UI but not from local storage

• All tasks are marked as completed

• All tasks are archived

• All tasks are deleted from both the UI and local storage

Which command is used to completely clear local storage?

• localStorage.reset

• localStorage.delete

• localStorage.clear

• localStorage.removeItem

What is the main benefit of using local storage in this task management application?

• It reduces the need for server-side storage

• It provides a secure way to store passwords

• It allows for real-time collaboration

• It enables offline access to tasks
