// // ==== 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(function(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 = runners.map((runner) => runner.first_name.toUpperCase());
// 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 = runners.filter(function(runners) {
//   return runners.shirt_size == "L";
// });
// 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,val) => {
//   return acc + val.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

// // Problem 2

// // Problem 3
