invoking a function at a designated interval

Question

invoking a function at a designated interval

I am currently working on a mobile application built with Ionic and TypeScript. My goal is to continuously update the user's location every 10 minutes.

My approach involves calling a function at regular intervals, like this:

function updateUserLocation(){
  // add your code here
  setTimeout(updateUserLocation, (1000 * 60) * 10);
}

updateUserLocation();

However, I have concerns about whether this function will still run even if the application is not actively being used. For example, if the user switches to another app, will this function continue to execute in the background?

If you need repetitive action in your code, consider utilizing the setInterval function. This function not only enables you to perform tasks at regular intervals but also provides the option to stop the repetition when needed:

function yourTask() { console.log("Repeating"); }
let intervalId = setInterval(yourTask, 100);
clearInterval(intervalId); // To halt the repetition

It is important to note that the current implementation of yourFunction creates a situation of infinite recursion, as it calls itself each time it runs.

A more efficient approach would be to utilize setInterval. By placing the function call outside of itself and utilizing the following code snippet:

function yourFunction(){
    // Perform necessary actions here
}

var intervalID = setInterval( function(){
    yourFunction();
}, (1000 * 60 * 10));

I personally lean towards utilizing

setInterval(yourFunction, time_in_milliseconds);

However, your approach should also function effectively when implemented in the following manner:

function yourFunction() {
   setTimeout(yourFunction, time_in_milliseconds);
} 
yourFunction();
