Iterate Asynchronously in Sequence

const tasks = []; // array of async tasks

function iterate(index) {
    if(index === tasks.length) {
        return finish();
    }

    const task = tasks[index];
    task(function() {
        // async callback: will execute when async task completes
        iterate(index + 1);
    });
}

function finish() {
    // iteration completed
}

iterate(0); // initiate series of async task execution
