 #### Example: Thumbs down gesture description 👎
 First, create a new GestureDescription object:
-```
+```javascript
 const thumbsDownGesture = new fp.GestureDescription('thumbs_down');
 ```
 Expect the thumb to be stretched out and pointing down:
-```
+```javascript
 thumbsDownGesture.addCurl(fp.Finger.Thumb, fp.FingerCurl.NoCurl);
 thumbsDownGesture.addDirection(fp.Finger.Thumb, fp.FingerDirection.VerticalDown, 1.0);
 ```
 This will define that a thumb pointing downwards will result in the highest score (1.0) for this gesture. If the thumb is angled diagonally down left / right we can somehow still accept it, albeit with a lower score (0.9).
-```
+```javascript
 thumbsDownGesture.addDirection(fp.Finger.Thumb, fp.FingerDirection.DiagonalDownLeft, 0.9);
 thumbsDownGesture.addDirection(fp.Finger.Thumb, fp.FingerDirection.DiagonalDownRight, 0.9);
 ```
 
 All other fingers are expected to be fully curled. For this gesture, it doesn't matter which direction the curled fingers are pointing at therefore only the curl description is added. Same as above, it's recommended to accept half-curled fingers too, with a little bit lower score.
-```
+```javascript
 // do this for all other fingers
 for(let finger of [fp.Finger.Index, fp.Finger.Middle, fp.Finger.Ring, fp.Finger.Pinky]) {
   thumbsUpDescription.addCurl(finger, FingerCurl.FullCurl, 1.0);
