# --description--

You can find the length of a `String` value by writing `.length` after the string variable or string literal.

```js
console.log("Alan Peter".length);
```

The value `10` would be displayed in the console.

For example, if we created a variable `const firstName = "Ada"`, we could find out how long the string `Ada` is by using the `firstName.length` property.

# --instructions--

Use the `.length` property to count the number of characters in the `lastName` variable and assign it to `lastNameLength`.

# --hints--

You should not change the variable declarations in the `// Setup` section.

```js
assert(
  code.match(/let lastNameLength = 0;/) &&
    code.match(/const lastName = "Lovelace";/)
);
```

`lastNameLength` should be equal to eight.

```js
assert(typeof lastNameLength !== 'undefined' && lastNameLength === 8);
```

You should be getting the length of `lastName` by using `.length` like this: `lastName.length`.

```js
assert(code.match(/=\s*lastName\.length/g) && !code.match(/lastName\s*=\s*8/));
```

# --seed--

## --seed-contents--

```js
// Setup
let lastNameLength = 0;
const lastName = "Lovelace";

// Only change code below this line
lastNameLength = lastName;
```

# --solutions--

```js
let lastNameLength = 0;
const lastName = "Lovelace";
lastNameLength = lastName.length;
```
