charlike/templates/node_modules/core-js/modules/_shared.js

Small, fast, simple and streaming project scaffolder for myself, but not only. Supports hundreds of template engines through the @JSTransformers API or if you want custom `render` function passed through options

var global = require('./_global')
  , SHARED = '__core-js_shared__'
  , store  = global[SHARED] || (global[SHARED] = {});
module.exports = function(key){
  return store[key] || (store[key] = {});
};
