<p>В отличие от строк, записи массивов <dfn>изменяемы</dfn> и могут быть изменены свободно. <strong>пример</strong> <pre class="language-js"><code>var ourArray = [50,40,30];

// Example
var ourArray = [18,64,99];
ourArray[1] = 45; // ourArray now equals [18,45,99].

// Setup
var myArray = [18,64,99];

// Only change code below this line.
