I'm running into some trouble trying to use modern javascript in the byond browser. It looks like byond is using internet explorer seven or eight as it's browser window.

Does anyone know which one?

Are there any plans on updating the browser soon? Those versions of internet explorer are tragically outdated at this point. Even Microsoft has given up on them.

it will render the page as version 8 for compatibility, but you can get it up to what ever version of IE you have installed on the computer. Just add this to your <head>

<meta http-equiv="x-ua-compatible" content="IE=edge">


And ie will disable the compatibility mode it adds to embedded pages.
Ah... ok, well that will help me. No plans to jump to webkit or chromium?
It's been attempted, but all attempts have born no fruit.
That's unfortunate, ah well. At least I can use React with compatibility mode turned off.
