Question

i created a notification box that it shows me an alert when i create a notification from the date which i create this notification.

For Example: i created the notification in 14:00 but it should appears automatically at 14:30.

how can i do it ? which technic should i do to make it?

thanks for your suggestion.

look into setTimeout(). It lets you execute a function after an interval in milliseconds. For example:

setTimeout(function(){
// show notification after half an hour
}, 30 * 60 * 1000)
