|
* 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 |
|
* @example |
|
* |
|
* // using apply |
|
* async.parallel([ |
|
* async.apply(fs.writeFile, 'testfile1', 'test1'), |
|
* async.apply(fs.writeFile, 'testfile2', 'test2') |
|
* ]); |
|
* |
|
* |
|
* // the same process without using apply |
|
* async.parallel([ |
|
* function(callback) { |
|
* fs.writeFile('testfile1', 'test1', callback); |
|
* }, |
|
* function(callback) { |
|
* fs.writeFile('testfile2', 'test2', callback); |
|
* } |
|
* ]); |
|

|
* // It's possible to pass any number of additional arguments when calling the |
|
* // continuation: |
|
* |
|
* node> var fn = async.apply(sys.puts, 'one'); |
|
* node> fn('two', 'three'); |
|
* one |
|
* two |
