intl.datetimeformat comma removed after version 20.11.1 #53083
Description
Version
20.11.2+
Platform
Darwin Darios-MacBook-Pro.local 22.6.0 Darwin Kernel Version 22.6.0: Wed Oct 4 21:25:26 PDT 2023; root:xnu-8796.141.3.701.17~4/RELEASE_X86_64 x86_64
Subsystem
intl.datetimeformate
What steps will reproduce the bug?
open terminal
confirm node version is above 20.11.1
node
node interface runs
d = new Date(Date.now())
formatted = new Intl.DateTimeFormat('en-GB', { dateStyle: 'full', timeStyle: 'medium' }).format(d)
output will show date string e.g. 'Tuesday 21 May 2024 at 09:55:02' with missing comma
If you repeat the process with 20.11.1 or below the output will be with a comma e.g. 'Tuesday, 21 May 2024 at 09:55:02'
How often does it reproduce? Is there a required condition?
every time
What is the expected behavior? Why is that the expected behavior?
output of formatted date should be (example) 'Tuesday, 21 May 2024 at 09:55:02'
What do you see instead?
I see instead (example) 'Tuesday 21 May 2024 at 09:55:02'

IIRC The I18N data is updated for every version, and compatibility isn't guaranteed
I might be wrong, cc @nodejs/i18n
ovflowd commentedon May 21, 2024
The @nodejs/i18n team is not responsible for this; the @nodejs/i18n-api is responsible for Node.js Core i18n APIs, afaik.
avivkeller commentedon May 21, 2024
My bad, sorry. I looked for i18n in the team list.
ovflowd commentedon May 22, 2024
All good, but I believe you're pretty on point with your explanation. I don't think this is a Node.js bug, but just a side-effect of the i18n data that comes with V8 (I believe that's where our Intl. APIs come from, including the i18n data for those APIs), I believe that the TextEncoder ones and others, come from Node.js itself.
targos commentedon May 22, 2024
More specifically, the data comes from ICU (a dependency of V8).

even more specifically, ICU's data comes from cldr, a dependency of ICU
