api

To memoize a function, require('memoize-clear'), and used the returned function to curry:

var memoize = require('memoize-clear'),
    memoized = memoize(function() { ... });

To clear the cache of one function, call .__clear() on that memoized function. You can also clear the cache of on function by passing it into memoize.clearCache(the function whose cache you want to clear). To clear the cache for all functions call .clearCache() on memoize itself.

var memoize = require('memoize'),
    storehouse = 1,
    memoized1 = memoize(function() { return storehouse; }),
    memoized2 = memoize(function() { return 2 * storehouse; });

memoized1(); // 1
memoized2(); // 2

storehouse = 3;

memoized1();    // 1

memoized1.__clear();

memoized1()     // 3
memoized2()     // 2

memoize.clearCache();

storehouse = 4;

memoized1()     // 4
memoized2()     // 8
