The default export for this module is a function that accepts three arguments
- array: _Array_ The first argument is the array to be looped through
- handlerFunction: _Function_ A function to handle all the items in the array. It also receives three arguments
- item: The current item in the array for the current index
- doneCallback: A callback function to indicate the current process is complete. Must be called to move to the next item.
This doneCallback(itemProcessingValue) can be passed a value to collect all the values returned after processing each item
- currentItemIndex: The index of the current item passed to the handlerFunction
- completeCallback: This is a function that depicts the whole items have been processed. It receives an array of all the return values passed when calling the doneCallback function of every item.
