Hi Shah,

Some context around the user journey through your application would be useful here but off the top of my head: -

  • Store data locally in cookies
  • POST the data to a server and store in a database

HTML5 also offers storage in the form of localStorage and sessionStorage

Here's some documentation on the latter: -

Great suggestions! I find that localStorage is really easy to use and set up (since it can be tested locally), especially if you lack experience with server-side scripts and databases.

JavaScript is a client-side language. An actual useful tool requires not just JavaScript but also knowledge of CSS for the styling as well as backend language (such as PHP) and knowledge of how an SQL database works.

As a way to learn JavaScript building a to-do list is a useful exercise.
