+To finish this challenge, it's necessary to use __character classes__. 
 
-<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds  -->
+The __\W__ matches any character that is not a word character from the basic Latin alphabet. 
+__Equivalent to [^A-Za-z0-9_].__
+
+For example, /\W/ or /[^A-Za-z0-9_]/ matches "%" in "50%".
+
+
+
+
+### Spoiiler Alert: Solution ahead
+```javascript
+let quoteSample = "The five boxing wizards jump quickly.";
+let nonAlphabetRegex = /\W/g; // Change this line
+let result = quoteSample.match(nonAlphabetRegex).length;
+```
