Can window.open open multiple tabs at once?

Question

Can I open a new window but with multiple tabs?

Something like this:

window.open("cnn.com;foxnews.com;nyt.com");

Answer 1

There's no concept of tab in standard DOM.

In fact when you ask the browser to open a window it might be a tab, depending on the browser and user settings.

So, apart writing extensions that the user will have to install, no, you can't do that.
