split-filter-n/example.js

Like Array#filter, but lets you categorize an array into any amount of smaller arrays

"use strict";

const splitFilterN = require("./");

let words = [
	"apple",
	"Banana",
	"strawberry",
	"Avocado"
];

let letterIndex = splitFilterN(words, ["A", "B", "C"], (word) => word[0].toUpperCase());

console.log(letterIndex);

/*
{
	A: [ 'apple', 'Avocado' ]
	B: [ 'Banana' ],
	C: [],
	S: [ 'strawberry' ]
}
*/
