Package Exports

trie-memoize

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (trie-memoize) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

trie-memoize

A memoizer in which each function argument represents a new key, creating a trie of caches as defined by your setup.

Installation

yarn add trie-memoize or npm i trie-memoize

Usage

const m1 = memoize([{}], v => v.toUpperCase())
m1('foo')  // FOO

const m2 = memoize([{}, Map], (v1, v2) => `${v1}-${v2}`)
m2('foo', 'bar')  // foo-bar

const m3 = memoize(
  [WeakMap, WeakMap, Map], 
  (v1, v2, v3) => `${JSON.stringify(v1)}-${JSON.stringify(v1)}-${JSON.stringify(v3)}`
)
let v1 = {}, v2 = {}, v3 = 'foo'
m3(v1, v2, v3)  // {}-{}-"foo"

`memoize(caches <Array>, fn <Function>)`

caches <Array>
- An array of plain objects or constructors used for caching each level of the tree. The first array element will be the cache for the first argument of the function, call, and so on. Therefore, the length of this array must be the same as the length of arguments your memoized function accepts.
- You may provide your own cache (e.g. not Map, WeakMap, {}). The only requirement is that it has get and set methods.
fn <Function>
- The function being memoized
