Edge browser doesn't run code

I can’t use freecodecamp.org with edge browser , the windows 10 main browser.
what is the problem.

Edge does not support many of the newer JavaScript features which the FCC curriculum site uses. It works best with Chrome.


Free Code Camp has been updated to use newer technologies. It makes the application much faster and it means that we can go much longer without having to do a huge migration like the recent one. However, Edge, Internet Explorer, and Safari are very bad about choosing not to adhere to standards and support new functionality in JS and CSS. Right now, that means that these browsers exhibit lots of unexpected behavior. If you become a web developer you will come to hate these browsers with every fiber of your being.
