Rememor

Simple memoization module, to speed up recursion, and calls to expensive functions.

---

Installation

1 $ npm install rememor

Usage

1    const remem = require('rememor');
2    //remem.doc(true) prints out a little info on the module.
3    let add = (a,b) => a + b;
4    const memAdd = remem.shallowRemem(add);
5    memAdd(1,2);
6    => 3
7    memAdd(1,2);
8    => 3 //But uses cache instead of calculating.
9    let fib = (n) => {
10        if(n !== 0 && n !== 1) {
11            return fib(n-2) + fib(n-1);
12        } else {
13            return n;
14        }
15    }
16    let memFib = remem.deepRemem(fib, 'fib');
17    //First argument is recursive function, second argument is the name
18    //of the recursive function to be replaced with the original function definition.
19    memFib(300);
20    => uses caches within function and returns in linear time.
21    let kindaLog = remem.kindaRemem(Math.log, null, .9);
22    //This is an approximation using memoization
23    kindaLog(.1000000007);
24    => //Calculates using original function
25    kindaLog(.1000000006);
26    => //Returns the cached value for the previous call because similar args.

Warning:

Be careful when using deepRemem, it modifies the function.
