//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.

// Convert each first name into all caps and log the result.

// Return an array named largeShirts that contains information about the runners that have a shirt size of L and log the result

// 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.

// Hint: use .map, .filter, and another .map.
