How to escape $ in the JS block yii2?

Question

$js = <<<JS
var $a = 'a';
JS;

We need to implement this syntax. But the $a is perceived as a php variable. How can I bypass this?

If the code does not need to use PHP variables, you need to wrap the JS after the <<< in single quotes:

$js = <<<'JS'
var $a = 'a';
JS;
