to_sentence

A JavaScript port of the Ruby activesupport #to_sentence method.

Converts an array to a comma-separated (or whatever-separated) sentence where the final element is joined by the connector word.

Also re-opens pendantic debate over the Oxford comma.

Install

npm install to_sentence

Usage

to_sentence(array, options) ==> String

where options is an object with any or all of the following keys:

words_connector - the string used to join elements 0 through array.length - 2 in an array with more than two elements (defaults to “, ”)
two_words_connector - the string used to join the elements in an array with exactly two elements (defaults to “ and ”)
last_word_connector - the string used to join array.length - 2 and array.length - 1 in an array with more than two elements (defaults to “, and ”)
locale - not yet implemented

Passing any other option will cause the method to throw an Error.

Examples

const to_sentence = require('to_sentence');

to_sentence([]);                
    // => ''

to_sentence(['Nelson Mandela']);
    // => 'Nelson Mandela'

to_sentence(['Nelson Mandela', 'an 800-year-old demigod'])
    // => 'Nelson Mandela and an 800-year-old demigod'

to_sentence(['Nelson Mandela', 'an 800-year-old demigod', 'a dildo collector'])
    // => 'Nelson Mandela, an 800-year-old demigod, and a dildo collector'
