JS task runner with setInterval there are two interval one runs every 10 seconds and then executes a function is your main task runner when that function is being executed and your tasks are running a check which is a boolean is set to true so it tells the other interval that major task runner function is running a task so dont call it now to ru…

//Major Function
const MajorLazer = async () => {

     if(NumberOfTasks != 0){

    //Set the check to true so interval which is running majorlazer fun become clear
    //then don't run the majorlazer multiple times causing errors or makig multiple calls
    check = true;
    var count = 0;
    var myTimer;

    (async () => {
        myTimer = setInterval(() => {

            console.log("Any Task Runs Here!");

            //check to stop the tasks runner function which is myTimer
            if (count >= NumberOfTasksYouHave) {
                console.log('Clearing the interval...');
                clearInterval(myTimer);
                console.log('Done!');
                //Set the check to false so interval which is was stop which is runing majorlazer function starts again
                check = false;
            }


        }, 1000);
        //This await delay is npm module it delays and pause any function further executing
        //Wait for interval to be executed and this delay should be equal to delay of interval
        //Because don't want count to be increamented before anytask finished
        await delay(1000);
        count++;
    })();
    }else{
    console.log("No new task available!");
    }
};


//Run this interval to run the main interval which is running the tasks
setInterval(() => {
    //if check is true means one scheduled task is running then concole log anything 
    if (check) {
