How to store JavaScript functions in a queue and execute in that order?

function myGFG() {

    // First function
    function function1() {
        console.log("First Function");
    }

    // Second function
    function function2() {
        console.log("Second Function");
    }

    let orderQueue = [];

    // Push them in queue
    orderQueue.push(function1);
    orderQueue.push(function2);

    while (orderQueue.length > 0) {
    
        // Execute in order
        orderQueue.shift()();
    }

    console.log("Functions executed in queue order");
}

myGFG();

function myGFG() {

    // First function
    function function1() {
        console.log("First Function");
    }

    // Second function
    function function2() {
        console.log("Second Function");
    }

    let functions = new Array();

    // Adding the functions in the order
    // in queue(array)
    functions[0] = function1;
    functions[1] = function2;
    
    for (let i = 0; i < functions.length; i++) {

        // Executing them in order.
        functions[i].call();
    }
    
    console.log("Functions executed in queue order");
}

myGFG();
