I am not 100% clear whether this belongs here or on Github, by reading the Security Policy though I'm posting this here.

The Bugbug bot thinks this bug should belong to the 'Core::JavaScript Engine' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Did you check what the file contains before reporting this bug ?
Please read:
https://github.com/mozilla/pdf.js/blob/master/external/builder/fixtures_babel/ifs-expected.js

It's probably a bug in Microsoft Defender.

Yeah I did and I figured it was a false positive, nonetheless I thought to report it.

Could you report it to Microsoft as a false positive?
