1.	Explain what is Lightning Out in the context of Salesforce Lightning.
Answer» Lightning Out is a feature that allows Lightning Apps to be extended. It operates as a connector, allowing Lightning Components to be accessed from any external web container. This means you may utilise your Lightning Components on an external SITE (such as SharePoint or SAP), in a HYBRID app built with the Mobile SDK, or even on Heroku or in a Visualforce Page. You may embed Lightning Components in an app across domains and manage interactions between the component and the app directly in the DOM using the Lightning Out JavaScript libraries. Your Lightning Components become substantially more effective with Lightning Out. You can utilise Lightning Components not only in other Lightning Components or Lightning Apps, but you can also EXPOSE them in almost any web container, on or off the App Cloud.
