# --description--
|
|
|
|
In order to get the last letter of a string, you can subtract one from the string's length.
|
|
|
|
For example, if `const firstName = "Ada"`, you can get the value of the last letter of the string by using `firstName[firstName.length - 1]`.
|
|
|
|
Example:
|
|
|
|
```js
|
|
const firstName = "Ada";
|
|
const lastLetter = firstName[firstName.length - 1];
|
|
```
|
|
|
|
`lastLetter` would have a value of the string `a`.
|
|
|
|
# --instructions--
|
|
|
|
Use <dfn>bracket notation</dfn> to find the last character in the `lastName` variable.
|
|
|
|
**Hint:** Try looking at the example above if you get stuck.
|
|
|
|
# --hints--
|
|
|
|
`lastLetterOfLastName` should be the letter `e`.
|
|
|
|
```js
|
|
assert(lastLetterOfLastName === 'e');
|
|
```
|
|
|
|
You should use `.length` to get the last letter.
|
|
|
|
```js
|
|
assert(__helpers.removeJSComments(code).match(/\.length/g).length > 0);
|
|
```

```js
|
|
// Setup
|
|
const lastName = "Lovelace";
|
|
|
|
// Only change code below this line
|
|
const lastLetterOfLastName = lastName; // Change this line
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
const lastName = "Lovelace";
|
|
const lastLetterOfLastName = lastName[lastName.length - 1];
|
|
```
