								In order to get the last letter of a string, you can subtract one from the string's length.
							 |

							 | 
							
							
								
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
							
								For example, if `var firstName = "Charles"`, you can get the value of the last letter of the string by using `firstName[firstName.length - 1]`.

								```js
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
							
								var firstName = "Charles";
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
							
								var lastLetter = firstName[firstName.length - 1]; // lastLetter is "s"
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
							
								```

								Use <dfn>bracket notation</dfn> to find the last character in the `lastName` variable.
