+//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:
+
+let numbers = [1, 2, 3, 4];
+let newNumbers = [];
+
+for (let i = 0; i < numbers.length; i++) {
+  if (numbers[i] % 2 !== 0) {
+    newNumbers.push(numbers[i] * 2);
+  }
+}
+
+console.log("The doubled numbers are", newNumbers); // [2, 6]
+
+// 1) Rewrite the above program using map and filter don't forget to use =>
+
+let numArray = [1, 2, 3, 4];
+let newNumbersArray = [];
+
+newNumbersArray = numArray.filter(value => value % 2 !== 0);       //an array of [1,3]
+console.log(newNumbersArray);
+
+var times2 = newNumbersArray.map(value => value * 2);               //1*2=3, 3*2=6. output 2, 6
+console.log("The doubled numbers are: " + times2);
+
+
+//Underneath you see a very interesting small insight in Maartje's work:

+];
+
+let tasks = monday.concat(tuesday);
+console.log(tasks);
+
+// 2) Write a program that does the following below. Use map and filter. You will also need a forEach or a for loop for the 'summing up' part.
+/*Collect two days' worth of tasks.
+Convert the task durations to hours, instead of minutes.
+Filter out everything that took less than two hours (i.e., remove from the collection)
+Multiply the each duration by a per-hour rate for billing (you can decide yourself what Maartje should make per hour) and sum it all up.
+Output a formatted Euro amount.
