Smelly Code

data = this.appendAnalyticsData(data);  
data = this.appendSubmissionData(data);  
data = this.appendAdditionalInputs(data);  
data = this.pruneObject(data);

↓

Nested Functions

data = this.pruneObject(  
  this.appendAdditionalInputs(
    this.appendSubmissionData(
      this.appendAnalyticsData(data)
    )
  )
);

↓

forEach

var funcs = [  
  this.appendAnalyticsData,
  this.appendSubmissionData,
  this.appendAdditionalInputs,
  this.pruneObject
];

funcs.forEach(function(func) {  
  data = func(data);
});

↓

Reduce

var funcs = [  
  this.appendAnalyticsData,
  this.appendSubmissionData,
  this.appendAdditionalInputs,
  this.pruneObject
];

data = funcs.reduce(function(memo, func) {  
  return func(memo);
}, data);

↓

Flow

data = _.flow(  
  this.appendAnalyticsData,
  this.appendSubmissionData,
  this.appendAdditionalInputs,
  this.pruneObject
)(data);
