Guidance for returning result from read

[Toshiba01]

Hi,

I need a little bit of guidance:

wire.read(length, function(err, res) { // result contains a buffer of bytes });

taking in consideration this function, how can I return result value to be used in the code outside of this function?

something like: var returnedValue = wire.read(length, function(err, res){ return res})

Thank you!

I'd recommend using Promises if you can't use the callback block.
