CoffeeScript: Can i pass parameters of a function while using async.parallel

Question

I am stuck with a very naive problem. Can we pass parameters to function while passing the functions through a function array in async.parallels. Below is a template code. While calling fn1 and fn2 in parallel, i want to pass parameters to each of them.

fn1 = (param , callback) ->
  #somethg 
  # callback

fn2 = (param , callback) ->
  #somethg 
  # callback

async.parallel [fn1 , fn2 ] , (err, result) ->
   # results aggregated from fn1 and fn2

Sure. Can you provide an example of what you'd like to accomplish? — Jonathan Lonowski

You can specify additional arguments by wrapping the call to each function in another, passing along the callback provided by async.parallel:

arg = 'foo'

async.parallel [
  callback -> fn1 arg, callback,
  callback -> fn2 arg, callback
], (err, result) ->
  console.log result
