bm-better-memoization

Overview

Wraps a function with a memoized function

setup

npm i -save bm-better-memoization

const m3m = require('bm-better-memoization');

Basic Example

our functions

let sum = (a, b) => ({sum: a + b});
let sum$ = m3m(sum);

using un-memoized function

let sum1 = sum(10, 3);
let sum2 = sum(10, 3);
// sum1 !== sum2;

using memoized function

let sum$1 = sum$(10, 3);
let sum$2 = sum$(10, 3);
// sum$1 === sum$2;

parameters

let thirteen = sum$(10, 3);
let five = sum$(2, 3);
let eleven = sum$(10, 1);
let elevenAgain = sum$(1, 10);
// thirteen !== five !== eleven !== elevenAgain

clearing cache

let four = sum$(2, 2);
let fourAgain = sum$(2, 2);
sum$.clear();
let fourAfter = sum$(2, 2);
let fourAfterAgain = sum$(2, 2);
// (four === fourAgain) !== (fourAfter === fourAfterAgain)
