function doSomething() {
  // this is the main function
};

//  Style A - shorter, but names don't directly match when they run, which may be confusing

doSomething.after(function() {
  //  this runs before doSomething
});

doSomething.before(function() {
  //  this runs after doSomething
});

//  Style B - more explicit names when reading the code, but less descriptive of what they do

doSomething.andThen(function() {
  //  this runs after doSomething
});

doSomething.butFirst(function() {
  //  this runs before doSomething
});
