Safari & BigInt

[MartyIX]

Hi,

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/BigInt is not supported on Safari supposedly. However, https://developer.apple.com/safari/technology-preview/release-notes/ mentions BigInt in Release 57 which was released AFAIK.

I'm not a Mac user. Maybe somebody can elaborate on what the current state of BigInt support in Safari is.

Regards,
M.

I suspect that these release notes are generated from a commit history. They might have a partial implementation of BigInt behind some flag for now.
https://bugs.webkit.org/show_bug.cgi?id=179001 is their tracking bug for that, and it still has a bunch of unresolved dependencies.

Safari 13 doesn't support BigInt objects as per manual testing (and I have not found any flags that can be enabled that would enable its support, so I'm thinking it's potentially a compilation flag). As such, I will be closing this issue.

I see lots of updates to BigInt support in the Safari TP release notes, but for some reason even as of Version 101 which is the latest, they do not appear to work.

const foo = 12n
< SyntaxError: No identifiers allowed directly after numeric literal
BigInt
< ReferenceError: Can't find variable: BigInt
BigInt(5)
< ReferenceError: Can't find variable: BigInt

Well, I guess they generate the release notes based on some commit log or on closed issues, without taking into account flags which make the feature unavailable.

@vinyldarkscratch given #4848 (comment) maybe this issue should actually be closed? (Of course anyone can still comment here after it’s closed.)

Sorry, good catch! I must have forgotten to hit “Close” before... 🤦‍♀️
