Spec
https://github.com/tc39/proposal-intl-datetime-style/
Summary
A Stage 3 proposal that adds two options to Intl.DateTimeFormat: dateStyle
and timeStyle. These options give a compact way to request the appropriate,
locale-specific way to ask for a date and time of given lengths
Example
let o = new Intl.DateTimeFormat("en" , {
timeStyle: "short"
});console.log(o.format(Date.now())); // "13:31"
let o = new Intl.DateTimeFormat("en" , {
dateStyle: "short"
});console.log(o.format(Date.now())); // "21.03.2012"
let o = new Intl.DateTimeFormat("en" , {
timeStyle: "medium",
dateStyle: "short"
});console.log(o.format(Date.now())); // "21.03.2012, 13:31"
Interoperability and compatibility risk
The two new options added to Intl.DateTimeFormat is new and should have no
risk to break pre-existing javascript code.
