public function AssetResolverInterface::getJsAssets

Returns the JavaScript assets for the current response's libraries.

References to JavaScript files are placed in a certain order: first, all 'core' files, then all 'module' and finally all 'theme' JavaScript files are added to the page. Then, all settings are output, followed by 'inline' JavaScript code. If running update.php, all preprocessing is disabled.

Note that hook_js_alter(&$javascript) is called during this function call to allow alterations of the JavaScript during its presentation. The correct way to add JavaScript during hook_js_alter() is to add another element to the $javascript array. See locale_js_alter() for an example of this.

Parameters

\Drupal\Core\Asset\AttachedAssetsInterface $assets: The assets attached to the current response. Note that this object is modified to reflect the final JavaScript settings assets.

bool $optimize: Whether to apply the JavaScript asset collection optimizer, to return optimized JavaScript asset collections rather than an unoptimized ones.

\Drupal\Core\Language\LanguageInterface $language: (optional) The interface language for the assets will be rendered with.

Return value

array A nested array containing 2 values:

• at index zero: the (possibly optimized) collection of JavaScript assets for the top of the page
• at index one: the (possibly optimized) collection of JavaScript assets for the bottom of the page
