this works, but because map returns a new array, just set the runners.map = a varaible, and you don't have to push to allCaps. the way you did it, a forEach() makes more sense to use. with map, it returns a new array.

console.log(allCaps);

// ==== Challenge 3: Use .filter() ====
// The large shirts won't be available for the event due to an ordering issue. Get a list of runners with large sized shirts so they can choose a different size. Return an array named largeShirts that contains information about the runners that have a shirt size of L and log the result
let largeShirts = [];
largeShirts = runners.filter((runner) => {
return runner.shirt_size === 'L';
})

console.log(largeShirts);

// ==== Challenge 4: Use .reduce() ====
// The donations need to be tallied up and reported for tax purposes. Add up all the donations into a ticketPriceTotal array and log the result
let ticketPriceTotal = [];

let donationTotal = runners.reduce(function(total, runners) {
return total + runners.donation;
}, 0);

ticketPriceTotal.push(donationTotal);

probably not necessary to push the donationTotal value into an array. what's the point of having a single value in an array?


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
// List all emails
let ListEmail = [];
runners.forEach(function(runner) {
ListEmail.push(runner.email);

usually capital variables refer to constructor functions. so i would keep it lowercase.

});

console.log(ListEmail);

// Problem 2
// List of donors of 250 or more dollars
let twofiftyorMore = runners.filter(x => x.donation > 250);

console.log(twofiftyorMore);

// Problem 3
// List of runners with long first names (greater than 7 letters) for custom name tags
let longfname = runners.filter((runner) => runner.first_name.length > 7);

// Problem 3
console.log(longfname);
