    Creates a function which is a composition of the passed asynchronous functions.

    Creates a function which is a composition of the passed asynchronous functions. Each function consumes the return value of the function that follows. Composing functions f(), g(), and h() would produce the result of f(g(h())), only this version uses callbacks to obtain the return values.

    Produces a new collection of values by mapping each value in coll through the iteratee function. The iteratee is called with an item from coll and a callback for when it has finished processing. Each of these callback takes 2 arguments: an error, and the transformed item from coll.

    Run the tasks collection of functions in parallel, without waiting until the previous function has completed. If any of the functions pass an error to its callback, the main callback is immediately called with the value of the error. Once the tasks have completed, the results are passed to the final callback as an array.

    tasks

    A collection containing functions to run. Each function is passed a callback(err, result) which it must call on completion with an error err (which can be null) and an optional result value.

    callback

    Creates a queue object with the specified concurrency.

    Creates a queue object with the specified concurrency. Tasks added to the queue are processed in parallel (up to the concurrency limit). If all workers are in progress, the task is queued until one becomes available. Once a worker completes a task, that task's callback is called.

    worker

    An asynchronous function for processing a queued task, which must call its callback(err) argument when finished, with an optional error as an argument. If you want to handle errors from an individual task, pass a callback to q.push(). Invoked with (task, callback).

    concurrency

    Calls callback on a later loop around the event loop.

    Calls callback on a later loop around the event loop. In Node.js this just calls setImmediate. In the browser it will use setImmediate if available, otherwise setTimeout(callback, 0), which means other higher priority events may precede the execution of callback.

    This is used internally for browser-compatibility purposes.

    callback

    The function to call on a later loop around the event loop.

    any number of additional arguments to pass to the callback on the next tick

    Runs the tasks array of functions in series, each passing their results to the next in the array. However, if any of the tasks pass an error to their own callback, the next function is not executed, and the main callback is immediately called with the error.

    tasks

    An array of functions to run, each function is passed a callback(err, result1, result2, ...) it must call on completion. The first argument is an error (which can be null) and any further arguments will be passed as arguments in order to the next task.

    callback

    An optional callback to run once all the functions have completed. This will be passed the results of the last task's callback (e.g. callback(err, [results])).
