Summary

Intl Locale Info API is a new Stage ECMAScript TC39 proposal to enhance the Intl.Locale object by exposing Locale information, such as week data (first day in a week, weekend start day, weekend end day, minimun day in the first week), and text direction hour cycle used in the locale. https://github.com/tc39/proposal-intl-locale-info We launch Intl Locale Info API w/ getters but later the proposal changed to rename these getters to functions. We need to deprecate the getter and relaunch the functions . The deprecation of getters is tracked in https://chromestatus.com/feature/5148228059398144
