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

 | 
					
						
							| 
									
										
										
										
											2021-05-29 09:03:21 -07:00
										 |  |  | For example, if `var firstName = "Ada"`, you can get the value of the last letter of the string by using `firstName[firstName.length - 1]`. |

										 |  |  | 
 | 
					
						
							|  |  |  | Example: | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							| 
									
										
										
										
											2021-05-29 09:03:21 -07:00
										 |  |  | var firstName = "Ada"; | 
					
						
							| 
									
										
										
										
											2021-03-02 16:12:12 -08:00
										 |  |  | var lastLetter = firstName[firstName.length - 1]; | 
					
						
							| 
									
										
										
										
											2020-03-25 08:07:13 -07:00
										 |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							| 
									
										
										
										
											2021-05-29 09:03:21 -07:00
										 |  |  | `lastLetter` would have a value of the string `a`. |

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

											2021-03-02 16:12:12 -08:00
										 |  |  | `lastLetterOfLastName` should be the letter `e`. | 
					
						
							| 
									
										
										
										
											2018-09-30 23:01:58 +01:00
										 |  |  | 
 |

											2020-11-27 19:02:05 +01:00

 | 
					
						
							| 
									
										
										
										
											2020-11-27 19:02:05 +01:00
										 |  |  | You should use `.length` to get the last letter. |
