Trails

const fountainValleyLoopTrail = {
  name: 'Fountain Valley Loop',
  location: 'Littleton, CO',
  distance: 2.3,
  traffic: 'moderate',
  features: ['bird watching', 'hiking', 'cross country skiing']
}

Level One

Write a function called displayTrailData that will take in any single object of trail data from above. It should return an array of strings. Passing in fountainValleyLoopTrail should return:

[ 
  'The trail name: Fountain Valley Loop',
  'The trail location: Littleton, CO',
  'The trail distance:  2.3',
  'The trail traffic: moderate',
  'The trail features: fishing, hiking, snowshoeing, bird watching'
 ];

Level Two

const favoriteActivities = [
 { name: 'hiking', preferenceLevel: 9  },
 { name: 'fishing', preferenceLevel: 7 },
 { name: 'snowshoeing', preferenceLevel: 0 },
 { name: 'bird watching', preferenceLevel: 6 },
]

Refactor your function so that you can pass in a second parameter of favoriteActivities. Sort the trail features by preferenceLevel so that my favorite activites show first. Now when you pass in fountainValleyLoopTrail and favoriteActivities, you should return the following, because hiking has the highest preference level.

[ 
'The trail name: Fountain Valley Loop',
 'The trail location: Littleton, CO',
 'The trail distance:  2.3',
 'The trail traffic: moderate',
 'The trail features: hiking, fishing, bird watching, snowshoeing'
];

Level Three

Refactor your function to remove activities that have a 0 preferenceLevel. Now when you pass in fountainValleyLoopTrail and favoriteActivities, you should return the following, because snowshoeing has a preferenceLevel of 0.

[ 
 'The trail name: Fountain Valley Loop',
'The trail location: Littleton, CO',
'The trail distance:  2.3',
'The trail traffic: moderate',
'The trail features: hiking, fishing, bird watching'
