Tracking the last time an app was run in Javascript can be achieved by creating a variable to store the date when

Exploring the world of Javascript as a newbie, I find myself with index.html, stylesheet.css and div.js in my app.

Within div.js lies a code that magically generates a schedule for our team members over 2 weeks. However, there's a catch - consistency is key. For example, if the table is created on May 9th, it should remain valid until May 25th. So when the application runs within this timeframe, I wish to receive an alert indicating that it has been previously executed. At this point, the user can either proceed with running it again or revert to the previous schedule.

I'm curious if achieving this behavior purely with Javascript is possible, or do I need to explore alternative techniques?

Answer №1

If you are not incorporating any server-side code, then unfortunately you will not be able to persist data using client-side code alone.

In the scenario of a single client, one potential option is to utilize cookies, although this may not be the most secure or recommended method due to inherent vulnerabilities. You can find more information on using cookies in JavaScript at http://www.w3schools.com/js/js_cookies.asp
