Repair broken instances of native JS constructors, making instanceof work!
Running code in different VMs will break the instance's reference.
Simply pass an instance or collection of instances to repair and instanceof
checks will run again. Although this sounds silly, consider a configuration
with multiple RegExp instances or dependencies that assume instanceof
checks to work.
npm install --save repair
var repair = require('repair')
, vm = require('vm')
, config = {};
vm.createContext(config);
vm.runInContext('date=new Date', config);
assert.equal(config.date instanceof Date, true, 'Different instance');
assert.equal(repair(config.date) instanceof Date, true);
