Examples

Using format

The following example shows how to create a List formatter using the English language.

const list = ['Motorcycle', 'Bus', 'Car'];

 console.log(new Intl.ListFormat('en-GB', { style: 'long', type: 'conjunction' }).format(list));
// > Motorcycle, Bus and Car

 console.log(new Intl.ListFormat('en-GB', { style: 'short', type: 'disjunction' }).format(list));
// > Motorcycle, Bus or Car

 console.log(new Intl.ListFormat('en-GB', { style: 'narrow', type: 'unit' }).format(list));
// > Motorcycle Bus Car

Using formatToParts

The following example shows how to create a List formatter returning formatted parts

const list = ['Motorcycle', 'Bus', 'Car'];
console.log(new Intl.ListFormat('en-GB', { style: 'long', type: 'conjunction' }).formatToParts(list));
 
// [ { "type": "element", "value": "Motorcycle" }, 
//   { "type": "literal", "value": ", " }, 
//   { "type": "element", "value": "Bus" },
//   { "type": "literal", "value": ", and " },
//   { "type": "element", "value": "Car" } ];
