// A local community center is holding a fund raising 5k fun run and has invited 50 small businesses to make a small donation on their behalf for some much needed updates to their facilities. Each business has assigned a representative to attend the event along with a small donation.
// Scroll to the bottom of the list to use some advanced array methods to help the event director gather some information from the businesses.

// ==== Challenge 1: Use .forEach() ====
// The event director needs both the first and last names of each runner for their running bibs. Combine both the first and last names and populate a new array called `fullNames`. This array will contain just strings.
let fullNames = [];
runners.forEach(runner => {
fullNames.push(`${runner.first_name} ${runner.last_name}`);
})
// console.log(fullNames);
// ==== Challenge 2: Use .map() ====
// The event director needs to have all the runners' first names in uppercase because the director BECAME DRUNK WITH POWER. Populate an array called `firstNamesAllCaps`. This array will contain just strings.
let firstNamesAllCaps = [];
firstNamesAllCaps = runners.map(runner => {
return `${runner.first_name.toUpperCase()} ${runner.last_name}`;
});
// console.log(firstNamesAllCaps);
// ==== Challenge 3: Use .filter() ====
// The large shirts won't be available for the event due to an ordering issue. We need a filtered version of the runners array, containing only those runners with large sized shirts so they can choose a different size. This will be an array of objects.
let runnersLargeSizeShirt = [];
runnersLargeSizeShirt = runners.filter(runner => {
if (runner.shirt_size === "L") {
return runner;
}
});
// console.log(runnersLargeSizeShirt);
// ==== Challenge 4: Use .reduce() ====
// The donations need to be tallied up and reported for tax purposes. Add up all the donations and save the total into a ticketPriceTotal variable.
let ticketPriceTotal = runners.reduce((acc, runner) => acc += runner.donation, 0);
// console.log(ticketPriceTotal);
// ==== Challenge 5: Be Creative ====
// Now that you have used .forEach(), .map(), .filter(), and .reduce().
// I want you to think of potential problems you could solve given the data set and the 5k fun run theme.
// Try to create and then solve 3 unique problems using one or many of the array methods listed above.
// Problem 1
let totalDonations = runners.reduce((acc, runner) => acc += runner.donation, 0);
let averageDonation = totalDonations / runners.length;
// console.log(averageDonation);
// Problem 2
function sortByDonation(arr, direction) {
switch (direction()) {
case 'asc': {
return arr.sort((a, b) => {
return (a.donation < b.donation) ? -1 : 1;
});
}
case 'desc': {
return arr.sort((a, b) => {
return (a.donation < b.donation) ? 1 : -1;
});
}
default: {
return 'Yeet';
}
}
}
function sortAscending() {
return 'asc';
}
function sortDescending() {
return 'desc';
}
// console.table(sortByDonation(runners, sortAscending));
// Problem 3
