How Can I Recursively Execute a JavaScript Function at Regular Intervals?

Executing a Function Recursively at Specified Time Intervals

In JavaScript, the setTimeout() function allows you to schedule a function call at a predefined time. This is useful when you need to perform an action after a specific delay. However, what if you want to execute a function repeatedly at regular intervals?

One approach is to use the setInterval() function:

setInterval(function, delay)

This function continuously invokes the specified callback function at the given time interval. However, this method can encounter issues if the function's execution time exceeds the interval.

A more reliable approach is to employ setTimeout() in conjunction with a self-executing anonymous function:

(function(){
    // Your code goes here
    setTimeout(arguments.callee, 60000);
})();

This function schedules the next call to the same function after the specified interval. It also ensures that the subsequent call is not made until the current function execution completes. The arguments.callee reference is used to call the function again, but it is deprecated in Ecmascript 5. A better alternative is to use a named function and reference it in the setTimeout call.
