How do I pass variables to JavaScript?

In your MODULENAME.module file:

$testVariable = 'himanshu'; drupal_add_js(array('MODULENAME' => array('testvar' => $testVariable)), array('type' => 'setting')); drupal_add_js(drupal_get_path('module', 'MODULENAME') . '/MODULENAME.js');

In MODULENAME.js file:

(function($) {   Drupal.behaviors.MODULENAME = {     attach: function (context, settings) {       alert(settings.MODULENAME.testvar);     }   }; })(jQuery);

this way you can pass your php variable in drupal javascript file and use the variable 🙂

How can I implement the above in Drupal 8?
