Arguments

• array - An array to iterate over
• iterator(item, callback, index) - A function called for each item in the array. The callback(err, value) optionally takes an error or data. Data is collected and provided when all iterator functions have finished. The index value is the index of the item in the array.
• callback(err, values) - The callback that is called when all iterator functions are finished or an error occurs. The values argument is an array of values collected from iterator functions. The index of the value in values maps to the index of the item provided to the iterator function.
