JavaScript Object Literals & Array Literals

Question

What is the difference between Object Literals and Array Literals in JavaScript? I know it has something to do with the length method but i don\'t fully understand it.

Answer 1

PHP's numeric array becomes an array literal or object literal in JavaScript

$ar = array('apple', 'orange', 'banana', 'strawberry');

echo json_encode($ar); // ["apple","orange","banana","strawberry"] - Array literal

echo json_encode($ar, **JSON_FORCE_OBJECT**); // {"0":"apple","1":"orange","2":"banana","3":"strawberry"} - Object Literal

PHP's associative array becomes an object literal in JavaScript

$book = array(
         "title" => "JavaScript: The Definitive Guide",
         "author" => "David Flanagan",
         "edition" => 6
        );

echo json_encode($book); // {title: "JavaScript: The Definitive Guide", author: "David Flanagan", edition: 6} - Object Literal
