// 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.map(a => `${a.first_name} ${a.last_name}`);
console.log(fullNames);
// ==== Challenge 2: Use .map() ====
// The event director needs to have all the runners' first names in uppercase because the director BECAME DRUNK WITH POWER. Populate an array called `firstNamesAllCaps`. This array will contain just strings.
let firstNamesAllCaps = runners.map(a => a.first_name.toUpperCase());
console.log(firstNamesAllCaps);
// ==== Challenge 3: Use .filter() ====
// The large shirts won't be available for the event due to an ordering issue. We need a filtered version of the runners array, containing only those runners with large sized shirts so they can choose a different size. This will be an array of objects.
let runnersLargeSizeShirt = runners.filter(a => a.shirt_size === "L");
console.log(runnersLargeSizeShirt);
// ==== Challenge 4: Use .reduce() ====
// The donations need to be tallied up and reported for tax purposes. Add up all the donations and save the total into a ticketPriceTotal variable.
let ticketPriceTotal = runners.reduce(function(accumulator, currentValue) {
return accumulator + currentValue.donation
}, 0);
console.log(ticketPriceTotal);
// ==== Challenge 5: Be Creative ====
// Now that you have used .forEach(), .map(), .filter(), and .reduce(). I want you to think of potential problems you could solve given the data set and the 5k fun run theme. Try to create and then solve 3 unique problems using one or many of the array methods listed above.
// Problem 1: Race organizer wants to email each participant and ask their company for a race sponsorship.
let emailComp = runners.map(a => `${a.email} ${a.company_name}`)
console.log(emailComp);
// Problem 2: Anyone who donated over $200 gets access to a VIP event after the race is over, create an array of these runners in order to email them their VIP tickets.
let vipList = runners.filter(a => a.donation >= 200);
console.log(vipList);
// Problem 3: Unfortunately the race falls on the same weekend as a Skinix company retreat and all Skinix employees dropped out of the race. They must be removed from the list of runners, but must remain in the original list to account for their donations.
let newRunners = runners.filter(a => a.company_name != "Skinix");
console.log(newRunners);
