gistfile1.txt

//Make a function that recursively invokes itself at the end on a timer
//This immediately invokes my_func, and then recursively invokes it at the end of the function after a 5 second delay.

(function my_func() {
    // your code
    setTimeout( my_func, 5000 );
})();

(function my_func() {
    // your code
    if( some_criteria_is_met ) {
        setTimeout( my_func, 5000 );
    }
})();
