+//We want to COMPLETELY reverse an array by flipping the order of the entries AND flipping the order of characters in each element.
+
+// Part One: Reverse Characters
+
+// 1. Define the function as reverseCharacters. Give it one parameter, which will be the string to reverse.
+// 2. Within the function, split the string into an array, then reverse the array.
+// 3. Use join to create the reversed string and return that string from the function.
+// 4. Below the function, define and initialize a variable to hold a string.
+// 5. Use console.log(reverseCharacters(myVariableName)); to call the function and verify that it correctly reverses the characters in the string.
+// 6. Optional: Use method chaining to reduce the lines of code within the function.
+
+// Part Two: Reverse Digits
+
+// 1. Add an if statement to reverseCharacters to check the typeof the parameter.
+// 2. If typeof is ‘string’, return the reversed string as before.
+// 3. If typeof is ’number’, convert the parameter to a string, reverse the characters, then convert it back into a number.
+// 4. Return the reversed number.
+// 5. Be sure to print the result returned by the function to verify that your code works for both strings and numbers. Do this before moving on to the next exercise.
+
+// Part Three: Complete Reversal
+
+// 1. Define and initialize an empty array.
+// 2. Loop through the old array.
+// 3. For each element in the old array, call reverseCharacters to flip the characters or digits.
+// 4. Add the reversed string (or number) to the array defined in part ‘a’.
+// 5. Return the final, reversed array.
+// 6. Be sure to print the results from each test case in order to verify your code.
+
+let arrayTest1 = ['apple', 'potato', 'Capitalized Words'];
+let arrayTest2 = [123, 8897, 42, 1168, 8675309];
+let arrayTest3 = ['hello', 'world', 123, 'orange'];
+
+// Bonus Missions
+
+// 1. Have a clear, descriptive name like funPhrase.
+// 2. Retrieve only the last character from strings with lengths of 3 or less.
+// 3. Retrieve only the first 3 characters from strings with lengths larger than 3.
+// 4. Use a template literal to return the phrase We put the '___' in '___'. Fill the first blank with the modified string, and fill the second blank with the original string.
+
+// Test Function
+
+// 1. Outside of the function, define the variable str and initialize it with a string (e.g. 'Functions rock!').
+// 2. Call your function and print the returned phrase.
+
+// Area of rectangle equal to length x width
+
+// 1. Define a function with the required parameters to calculate the area of a rectangle.
+// 2. The function should return the area, NOT print it.
+// 3. Call your area function by passing in two arguments - the length and width.
+// 4. If only one argument is passed to the function, then the shape is a square. Modify your code to deal with this case.
+// 5. Use a template literal to print, “The area is ____ cm^2.”
