What happend to glitch editor

sorry but the glitch editor seems to work like a normal note book when i try to use and array it doesn’t add a closing one
ex: if i warite “{” it just leave it like that without finishing with “}”

Yeah it was removed a while back.
And I opened a similar issue and got to know that it was removed, though there is a temporary method of making it happen (You should do it every time you refresh the browser)

Open the console in your browser and type

application.editor().setOption("autoCloseBrackets", true)

And you will be able to see what you wanted, but as stated earlier, you will have to do it every time you refresh your broswer tab.

Yes, it was turned off as some users reported it being more of a hindrance than a help, some discussion here: Auto completion?
