javascript - Promises, pass additional parameters to then chain

Question

A promise, just for example:

var P = new Promise(function (resolve, reject) {
  var a = 5;
  if (a) {
    setTimeout(function(){
      resolve(a);
    }, 3000);
  } else {
    reject(a);
  }
});

After we call the .then() method on the promise:

P.then(doWork('text'));

Then doWork function looks like this:

function doWork(data) {
  return function(text) {
    // sample function to console log
    consoleToLog(data);
    consoleToLog(b);
  }
}

How can I avoid returning an inner function in doWork, to get access to data from the promise and text parameters? Are there any tricks to avoiding the inner function?

Answer 1

Perhaps the most straightforward answer is:

P.then(function(data) { return doWork('text', data); });

Or, since this is tagged ecmascript-6, using arrow functions:

P.then(data => doWork('text', data));

I find this most readable, and not too much to write.
