Javascript Equivalent of PHP's list() function

PHP's list() function allows for the assignment of multiple variables from an array. For example:

<code class="php">$matches = array('12', 'watt');
list($value, $unit) = $matches;</code>

This assigns the first element of the $matches array to the $value variable, and the second element to the $unit variable.

Is there a similar function in Javascript?

Answer:

Yes, there is a Javascript equivalent of the list() function in newer versions of Javascript called destructuring assignment. This feature is supported in Mozilla-based browsers and Rhino.

To use destructuring assignment, you use the following syntax:

<code class="javascript">[a, b] = [b, a];</code>

This will swap the values of the a and b variables.

Note:

Destructuring assignment is not supported in Internet Explorer. However, it is supported in all other modern browsers.
