charlike/templates/node_modules/core-js/modules/_shared-key.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 shared = require('./_shared')('keys')
  , uid    = require('./_uid');
module.exports = function(key){
  return shared[key] || (shared[key] = uid(key));
};
