Task Functions

Every task function will receive two arguments. Task is an ask-for-promise object and controls execution of queue. Resolving the promise will start next task. Data is available for all functions in task list.

let myTask = ( task, data ) => {
           // ... do something here
           task.done ( 'myTaskResult' )   // finishing the task. Provide result if needed 
           // return task.promise // --> if function has asynchronous code and we have to wait until it is done
     }
