|
* Creates a continuation function with some arguments already applied.
|
||
|
|
*
|
||
|
|
* Useful as a shorthand when combined with other control flow functions. Any
|
||
|
|
* arguments passed to the returned function are added to the arguments
|
||
|
|
* originally passed to apply.

|

|
|
* @param {Function} fn - The function you want to eventually apply all
|
||
|
|
* arguments to. Invokes with (arguments...).
|
||
|
|
* @param {...*} arguments... - Any number of arguments to automatically apply
|
||
|
|
* when the continuation is called.
|
||
|
|
* @returns {Function} the partially-applied function
|

|
||
|
|
*
|
||
|
|
* // using apply
|
||
|
|
* async.parallel([

|
|

|
||
|
|
*
|
||
|
|
* // the same process without using apply
|
||
|
|
* async.parallel([

* fs.writeFile('testfile1', 'test1', callback);

|
* node> var fn = async.apply(sys.puts, 'one');
