listify

What is listify?

The listify npm package is a utility that converts arrays into human-readable lists. It is particularly useful for formatting lists in a way that is grammatically correct and easy to read.

What are listify's main functionalities?

Basic List Formatting

This feature allows you to convert an array of items into a human-readable list. By default, it uses commas to separate items and adds 'and' before the last item.

const listify = require('listify');
const items = ['apple', 'banana', 'cherry'];
console.log(listify(items)); // Output: 'apple, banana, and cherry'

Custom Separator

This feature allows you to specify a custom separator for the list items. In this example, a semicolon followed by a space is used as the separator.

const listify = require('listify');
const items = ['apple', 'banana', 'cherry'];
console.log(listify(items, { separator: '; ' })); // Output: 'apple; banana; and cherry'

Custom Final Word

This feature allows you to customize the final word used before the last item in the list. In this example, 'or' is used instead of the default 'and'.

const listify = require('listify');
const items = ['apple', 'banana', 'cherry'];
console.log(listify(items, { finalWord: 'or' })); // Output: 'apple, banana, or cherry'

Oxford Comma

This feature allows you to enable or disable the Oxford comma. By setting oxfordComma to false, the comma before the final word is omitted.

const listify = require('listify');
const items = ['apple', 'banana', 'cherry'];
console.log(listify(items, { oxfordComma: false })); // Output: 'apple, banana and cherry'
