Change Details

Steps to reproduce: 1. Open your [[https://en.wikipedia.org/wiki/Special:MyPage/common.js|Special:MyPage/common.js]] for editing, add the code ``` var val, a = ['a', 'b']; for (val of a) { console.log(val); } ``` 2. Preview your change. The console should show "a" and "b" (given your browser support that much of ES6, but most browsers should, by now). 3. Save the page. Expected result: Same as step 2. Actual result: The code from common.js is replaced with code that just throws an error: `Error: JavaScript parse error: Parse error: Unexpected token; token ; expected in file 'Benutzer:Schnark/common.js' on line 5` While for the site wide MediaWiki:Common.js etc. this is a good feature (to make sure nobody accidentally puts in some ES6 features only available in his browser but not in other users' browser), for personal JS a user should not be prevented to use whatever features his browser is able to provide. #### Status //"[As of April 2021] the JS syntax checker blocks use of ES6 in (i) gadgets, (ii) sitewide JS pages and (iii) user common.js page. "// #### Workaround See T75714#4674421. Gist: deactivate the js validators is possible but has risks.
