...however tracking errors and the varying way of passing data through for control flow causes development to sometimes be very difficult.

I've recently created a simple abstraction named "wait.for" to call async functions in sync mode (based on Fibers): https://github.com/luciotato/waitfor

Using wait.for, you can use 'try/catch' while still calling async functions, and you keep function scope (no closures needed). Example:

function inAFiber(param){
  try{
     var data= wait.for(fs.readFile,'someFile'); //async function
     var result = wait.for(doSomethingElse,data,param); //another async function
     otherFunction(result);
  }
  catch(e) {
     //here you catch if some of the "waited.for" 
     // async functions returned "err" in callback
     // or if otherFunction throws
};
