+To finish this challenge, it's necessary to use __boundaries__. 
 
-<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds  -->
+The __$__ Matches end of input. 
+
+For example, /t$/ does not match the "t" in "eater", but does match it in "eat". 
+
+
+__important:__ If the multiline flag is set to true, also matches immediately before a line break character.

+### Spoiiler Alert: Solution ahead
+```javascript
+let caboose = "The last car on a train is the caboose";
+let lastRegex = /caboose$/; // Change this line
+let result = lastRegex.test(caboose);
+```
