How to execute Promise.all from object array methods?

Question

htaccess

There is an array of objects of type

{
...
 action: async function() {...}
}

Let's call it objs
How can I do something like Promise.all (objs.action)so that they all start executing at the same time
The only thing that comes to mind is

let does = objs.map( e => e.action.bind(e));
let results = await Promise.all(does)

But it doesn't work.

Answer 1

RewriteEngine On
RewriteCond %{REQUEST_URI} /tg/(.+)$ [OR,NC]
RewriteCond %{REQUEST_FILENAME} !/tg\.php$
RewriteRule ^(.*)$ /tg.php [L]

RewriteCond %{REQUEST_URI} /vk/(.+)$ [OR,NC]
RewriteCond %{REQUEST_FILENAME} !/vk\.php$
RewriteRule ^(.*)$ /vk.php [L]

Answer 2

e.action.call(e)
bind does not call the function...
