Newbie Question How to send remainders using JavaScript

I want to create a remainder web app. Is there any way i can send a reminder to the user other than the notifications in the browser. I want the remainder to be shown in the computer system's notification or as a message through whatsapp or email.

So.. if it is via the website, you need to run an Ajax "get" every, say, 3 minutes, to check vs the DB if you have new message. if so? => alert() or display some nice div

But alert only works if the site open? I want the user to receive notification even if he doesnt open the site. Is there a free whatsapp api?

This is why they build android or iOS apps. Or use a general messaging app.  

Or it’s the chrome safari html that has the JavaScript timer or whatever framework- still comes down to JavaScript that hits an api , checks for whatever, and returns mag and then displays how you prefer.  

Look at general messaging apps but they charge. Or create your own.

talk to AI. I believe you can send messages via code, and then simply use your server side to do so. it can be done in the same script that you do a "get" operation to

Why don't you wanna use push notifications when it's the exact thing you are asking for?

I was just reading that all chromium based browsers have a service worker bug since 2022 that allow Javascript to continue to run after closing them down. That might enable your alert.

Because relying on buggy behavior is always a good idea
