localeTitle: Найти длину строки

## Description
<section id='description'>
Вы можете найти длину значения <code>String</code> , написав <code>.length</code> после строковой переменной или строкового литерала. <code>&quot;Alan Peter&quot;.length; // 10</code> Например, если мы создали переменную <code>var firstName = &quot;Charles&quot;</code> , мы могли бы узнать, как долго строка <code>&quot;Charles&quot;</code> используется с использованием свойства <code>firstName.length</code> .
</section>
## Instructions
<section id='instructions'>
Используйте свойство <code>.length</code> чтобы подсчитать количество символов в переменной <code>lastName</code> и назначить его <code>lastNameLength</code> .
</section>
## Tests
<section id='tests'>
```yml
tests:
- text: You should not change the variable declarations in the <code>// Setup</code> section.
testString: assert(code.match(/var lastNameLength = 0;/) && code.match(/var lastName = "Lovelace";/));
- text: <code>lastNameLength</code> should be equal to eight.
testString: assert(typeof lastNameLength !== 'undefined' && lastNameLength === 8);
- text: 'You should be getting the length of <code>lastName</code> by using <code>.length</code> like this: <code>lastName.length</code>.'
testString: assert(code.match(/=\s*lastName\.length/g) && !code.match(/lastName\s*=\s*8/));
```

## Challenge Seed
<section id='challengeSeed'>
<div id='js-seed'>
```js
// Example
var firstNameLength = 0;
var firstName = "Ada";
firstNameLength = firstName.length;
// Setup
var lastNameLength = 0;
var lastName = "Lovelace";
// Only change code below this line.
lastNameLength = lastName;
```
</div>
</section>
## Solution
<section id='solution'>
```js
var firstNameLength = 0;
var firstName = "Ada";
firstNameLength = firstName.length;
var lastNameLength = 0;
var lastName = "Lovelace";
lastNameLength = lastName.length;
