How can dangerous scripts be prevented from being inserted into text using TinyMCE?

To prevent dangerous scripts from being inserted into text using TinyMCE, you can use the `valid_elements` setting to restrict the types of HTML elements and attributes that are allowed. By specifying only safe elements and attributes, you can prevent users from inserting potentially harmful scripts. 

// Initialize TinyMCE with custom valid_elements setting to prevent dangerous scripts
$initArray = array(
    'valid_elements' => 'a[href|target=_blank],strong/b,em/i,p,br',
);

wp_editor($content, 'editor_id', array('tinymce' => $initArray));
