| # --description--
 | |
| 
 | |
| You can also use <dfn>bracket notation</dfn> to get the character at other positions within a string.
 | |
| 
 | |
| Remember that computers start counting at `0`, so the first character is actually the zeroth character.
 | |
| 
 | |
| Example:
 | |
| 
 | |
| ```js
 | |
| var firstName = "Ada";
 | |
| var secondLetterOfFirstName = firstName[1];
 | |
| ```
 | |
| 
 | |
| `secondLetterOfFirstName` would have a value of the string `d`.
 | |
| 
 | |
| # --instructions--
 | |
| 
 | |
| Let's try to set `thirdLetterOfLastName` to equal the third letter of the `lastName` variable using bracket notation.
 | |
| 
 | |
| **Hint:** Try looking at the example above if you get stuck.
 | |
| 
 | |
| # --hints--
 | |
| 
 | |
| The `thirdLetterOfLastName` variable should have the value of `v`.
 | |
| 
 | |
| ```js
 | |
| assert(thirdLetterOfLastName === 'v');
 | |
| ```
 | |
| 
 | |
| You should use bracket notation.
 | |
| 
 | |
| ```js
 | |
| assert(code.match(/thirdLetterOfLastName\s*?=\s*?lastName\[.*?\]/));
 | |
| ```
 | |
| 
 | |
| # --seed--
 | |
| 
 | |
| ## --after-user-code--
 | |
| 
 | |
| ```js
 | |
| (function(v){return v;})(thirdLetterOfLastName);
 | |
| ```
 | |
| 
 | |
| ## --seed-contents--
 | |
| 
 | |
| ```js
 | |
| // Setup
 | |
| var lastName = "Lovelace";
 | |
| 
 | |
| // Only change code below this line
 | |
| var thirdLetterOfLastName = lastName; // Change this line
 | |
| ```
 | |
| 
 | |
| # --solutions--
 | |
| 
 | |
| ```js
 | |
| var lastName = "Lovelace";
 | |
| var thirdLetterOfLastName = lastName[2];
 | |
| ```
