{"library":"lodash._createcache","title":"Lodash Internal Create Cache Module","description":"lodash._createcache is a modularized internal utility from the Lodash v3 ecosystem, specifically version 3.1.2, last published approximately seven years ago (around 2019). Its original purpose was to provide a standalone CommonJS module for Lodash's internal cache creation logic, often used by functions like `_.memoize`. Unlike the main Lodash library (currently at v4.18.1), which is actively maintained with a regular release cadence, `lodash._createcache` is an abandoned package and no longer receives updates, bug fixes, or security patches. Developers should be aware that its functionality and API are deeply tied to the older Lodash v3 implementation and are not guaranteed to be compatible or safe with modern Lodash versions (v4+) or contemporary JavaScript environments. It serves primarily as a historical artifact of Lodash's modularization efforts during its v3 era.","language":"javascript","status":"abandoned","last_verified":"Tue Apr 21","install":{"commands":["npm install lodash._createcache"],"cli":null},"imports":["const createCache = require('lodash._createcache');"],"auth":{"required":false,"env_vars":[]},"quickstart":{"code":"const createCache = require('lodash._createcache');\n\n// In Lodash v3, a cache created by `createCache` typically provided\n// methods like `get`, `set`, and `has`.
