 | 
					
						
							|  |  |  | Remember that computers start counting at `0`, so the first character is actually the zeroth character. |

							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | var firstName = "Ada"; | 
					
						
							|  |  |  | var secondLetterOfFirstName = firstName[1]; // secondLetterOfFirstName is "d" |

										 |  |  | Let's try to set `thirdLetterOfLastName` to equal the third letter of the `lastName` variable using bracket notation. |
