How Can I Call a JavaScript Function at Regular Intervals?

Calling a Function at Regular Intervals

In JavaScript, the setTimeout() function allows you to execute a callback function after a specified delay. However, when you want to call a function repeatedly at a regular interval, you have two options to consider.

setInterval()

If the code within your timer may take longer than your interval, you can use setInterval().

setInterval(function, delay);

This function will repeatedly execute the specified callback function at the given delay.

setTimeout() with Anonymous Recursion

A more efficient approach is to use setTimeout() along with a self-executing anonymous function:

(function(){
    // Execute some code
    setTimeout(arguments.callee, 60000);
})();

This method guarantees that the next call is not made before your code has finished executing. Here, arguments.callee is used as a reference to the function, ensuring proper invocation in setTimeout().
