 // ==== 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 into a new array called fullName.

 // The event director needs to have all the runner's first names converted to uppercase because the director BECAME DRUNK WITH POWER. Convert each first name into all caps and log the result

 // ==== 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

 // ==== 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 solve 3 unique problems using one or many of the array methods listed above.
 
 // Problem 1
+//Get the company names in alphabetical order. 
+let companyNames = []; 
+runners.forEach(function (runner){
+  companyNames.push(runner.company_name.toLowerCase());
+});
+console.log(companyNames.sort());
 
 // Problem 2
+//Get donation for every runner over 200 Each runner that got over 200 donation gets a special certificate  to say thanks. Need to send out email  Get email address for each runner over 200. 
+let y = false;
+let bigDonations = [];  
+runners.filter( x => x.donation > 200 ? bigDonations.push(x.email) : y=false );

+// Problem 3  taxes on the donations is 7% or .07 calculate the tax for each runners donation  and then added it to their information.
