Intl.ListFormat.prototype.format()

list

An iterable object, such as an Array.

A language-specific formatted string representing the elements of the list

The format() method returns a string that has been formatted based on parameters provided in the Intl.ListFormat object. The locales and options parameters customize the behavior of format() and let applications specify the language conventions that should be used to format the list.

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
