Why are async functions considered invalid/unrecognized by MediaWiki's parser?

var function = async function(){

}

"JavaScript parse error: Parse error: Missing ; before statement in file"

I think so - I always see that error (and ignore it)

I can't ignore it, because I need a async function.

I mean I ignore the error, because the code works fine

I can't ignore it, because if this error occurs it never executes the code

It isn't executed for you? It always is for me...

Yeah, it simply throws this error

JavaScript parse error: Parse error: Missing ; before statement in file 'User:FunPL/common.js' on line 37

and it doesn't execute the code.

case you post a snippet of the code?

async function help(){

alert("Works?")

}

help()

Tested this snippet just now and it doesn't work, if I remove 'async' it works

in this case you truly are missing semicolons - you need one at the end of alert, and another after you call help

Still doesn't work. Tested it

MediaWiki JS pages are still on ES5. They do not officially support syntax that is newer than that.
