								In the last challenge, you learned to use the caret character to search for patterns at the beginning of strings. There is also a way to search for patterns at the end of strings.

								You can search the end of strings using the dollar sign character `$`  at the end of the regex.

								let storyRegex = /story$/;
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								storyRegex.test(theEnding);

								The first `test`  call would return `true` , while the second would return `false` .

								Use the anchor character (`$` ) to match the string `caboose`  at the end of the string `caboose` .

								You should search for `caboose`  with the dollar sign `$`  anchor in your regex.
