Export as

Export as

Named exports also conveniently offer a way to change the name of variables when we export or import them. We can do this with the as keyword.

Let’s see how this works. In our menu.js example

 

 

let specialty = '';
let isVegetarian = function() {
}; 
let isLowSodium = function() {
}; 

export { specialty as chefsSpecial, isVegetarian as isVeg, isLowSodium };

 

 

In the above example, take a look at the export statement at the bottom of the of the file.

1. The as keyword allows us to give a variable name an alias as demonstrated in specialty as chefsSpecial and isVegetarian as isVeg.
2. Since we did not give isLowSodium an alias, it will maintain its original name.

 let availableAirplanes = [
{
  name: 'AeroJet',
  fuelCapacity: 800,
  availableStaff: ['pilots', 'flightAttendants', 'engineers', 'medicalAssistance', 'sensorOperators'],
  maxSpeed: 1200,
  minSpeed: 300
 }, 
 {name: 'SkyJet',
  fuelCapacity: 500,
  availableStaff: ['pilots', 'flightAttendants'],
  maxSpeed: 800,
  minSpeed: 200
 }
];


 let flightRequirements = {
  requiredStaff: 4,
  requiredSpeedRange: 700
};

 function meetsStaffRequirements(availableStaff, requiredStaff) {
  if(availableStaff.length >= requiredStaff){
    return true;
  }else {
    return false;
  }
  }



 function meetsSpeedRangeRequirements(maxSpeed, minSpeed, requiredSpeedRange){
  let range = maxSpeed - minSpeed;
  if(range > requiredSpeedRange){
    return true;
  }else{
    return false;
  }
}

export { availableAirplanes as aircrafts, flightRequirements as flightReqs, meetsStaffRequirements as meetsStaffReqs, meetsSpeedRangeRequirements as meetsSpeedRangeReqs };
