 1. Say you would like to write a program that doubles the odd numbers in an array and throws away the even number.
 
-Your solution could be something like this:
-```js
-let numbers = [1, 2, 3, 4];
-let newNumbers = [];

-for(let i = 0; i < numbers.length; i++) {

-2. Use the array of the previous assignment, write a program that add the even numbers to the resulting array twice, but the odd numbers only once. Don't forget to use `=>`.

 - Collect two days' worth of tasks.
 - Convert the task durations to hours, instead of minutes.
-- Filter out everything that took two hours or more.
-- Sum it all up.
-- Multiply the result by a per-hour rate for billing (you can decide yourself what Maartje should make per hour).
