 ## Check for All or None
 
+With Regular Expressions (RegExp) you can have modify your testing pattern with special charaters. To pass this challenge you the __quantifiers__ are very helpful. A quantifier is __?__ in __x?__.
 
-### Hint:
+__x?__ Matches the preceding item x 0 or 1 time.
-The difference between american and british English for the given word is: favorite-favourite. We need to define the existance of the letter u .
+
+For example, /e?le?/ matches the "el" in "angel" and the "le" in "angle."
+
+If used immediately after any of the quantifiers *, +, ?, or {}, makes the quantifier non-greedy (matching the minimum number of times), as opposed to the default, which is greedy (matching the maximum number of times).  
+ 
+
+__Challenge Solution:__  
 
-## Solution
 ```javascript
 let favWord = "favorite";
 let favRegex = /favou?rite/; // Change this line
