Spec
https://tc39.github.io/proposal-intl-list-format
Summary
A Stage 3 proposal that introduces a new formatter under Intl.
Intl.ListFormat helps libraries and frameworks format a list in a
localized fashion by providing internationalized messages using a customary
local word or phrase when available. For example, calling its format()
method with ["Alice", "Bob", "Charlie", "Delta"] would return the string
"Alice, Bob, Charlie and Delta" in English.
Example
let lf = new ListFormat("en");
lf.format(["Alice"]);
// > "Alicce"
lf.format(["Alice", "Bob"]);
// > "Alice and Bob"
lf.format(["Alice", "Bob", "Charlie"]);
// > "Alice, Bob and Charlie"
lf.format(["Alice", "Bob", "Charlie", "Delta"]);
// > "Alice, Bob, Charlie and Delta"
lf = new ListFormat("zh");
lf.format(["譚永鋒"]);
// > "譚永鋒"
lf.format(["譚永鋒", "劉新宇"]);
// > "譚永鋒和劉新宇"
Interoperability and compatibility risk
The Intl.ListFormat is new and should have no risk to break pre-existing
javascript code.
