+
+
+
+
+Implement a function that can detect whether an image is landscape.
+The function should take two parameters: the width and height of an image. 
+
+If it the width parameter returns true, then the image is landscape
+(which means width is greater than height). 
+Otherwise - if the height is greater than the width - it returns false.

+// With comments:

+function isLandscape(width, height) {
+  // 1. Create a conditional ternary operator
+  //    explicit: (width > height) ? true : false 
+  //    implicit: (width > height)
+
+  // 2. Store the value of the expression in a variable
+  const calculateRatio = (width > height);
+
+  // 3. Use an 'if...else' conditional statement to display different messages.  
+  if(calculateRatio) {
+    return 'Your image is portrait.';
+  } else {
+    return 'Your image is landscape.';
