Functional way of reducing array to list.

string_reduce.js

// Not really sure how I feel about this but it's kinda cool...
const prettyList = function(list, conjunction) {
  return list.reduce((acc, str, i, arr) => (
				arr.length - i == 1 ? 
					`${acc}${conjunction} "${str}"` : 
					`${acc}"${str}", `
				), 
				"");
} 

prettyList(["apples", "pears", "oranges", "bananas"], "and") // "apples", "pears", "oranges", and "bananas"
