            Bug ID: 209774
           Summary: Unified Intl.NumberFormat missing in WebKit
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: sffc at chromium.org

Unified Intl.NumberFormat, the proposal which adds compact notation, measurement units, and a handful of other options to Intl.NumberFormat, has reached Stage 4 in TC39 as of February 2020, and the other major browser engines (V8 and SpiderMonkey) have been shipping it for some time.

As usage of these features of Intl.NumberFormat increases throughout the ecosystem, WebKit users will be left behind with legacy polyfills, leading to poorer performance relative to other browsers.  At Google, we are currently weighing our options for calling these features of Intl.NumberFormat in supported environments in order to give users better performance and smaller download sizes.

ICU4C exposes C and C++ APIs that can be used to implement Unified Intl.NumberFormat.  Implementing Unified Intl.NumberFormat is largely a matter of adding the glue between JavaScript and ICU4C, as WebKit already does for other Intl types.
