Memoization Test

Memoize a slow function with callback in its arguments.

Note. The callback on the function must be the first argument.

Installation

npm install memoize_test

Usage

The input of memoize is slow_function and the output is a faster function.

memoize = require('memoize_test')
 
fast_function = memoize(slow_function); // runs faster than slow_function by using cache functions

You can also pass the TTL. The default one will be 5 seconds.

fast_function = memoize(slow_function,{ttl:2000}); // Time to live set to 2 seconds

Different case

We can also assume that sometimes the cache function can be slower than the slow_function.In this situation both the cache_retrieve and slow_fn will be called and the first being completed will be used. To see a solution for this case, take a look at better_memoization.coffee

For test purpose if you're running better_memoization.coffee the number 2 will always simulate the cache function being slower.
