<p>Хорошей практикой является объявление переменной вместе с инициализацией её начальным значением. Код <pre class="language-js"><code>var myVar = 0;</code></pre> создает новую переменную <code>myVar</code> и присваивает ей начальное значение <code>0</code> .</p></section>

// Example
var ourVar = 19;

// Only change code below this line
