Easily convert your list of string values into a grammatically correct string. So if your list looks like ["milk", "eggs", "bread", "toilet paper"], then you can directly add it to an output as a single string: "milk, eggs, bread, and toilet paper".
const oxfordJoin = require(`oxford-comma-join`);
console.log(oxfordJoin([`one`, `two`, `three`, `four`]));
// "one, two, three, and four"
const oxfordJoin = require(`oxford-comma-join`);
console.log(oxfordJoin([`one`, `two`, `three`, `four`]));
// "one, two, three, and four"
console.log(oxfordJoin([`one`, `two`]));
// "one and two"
