Here important point is that ltng:outApp needs to be extended in app.

ltng:outApp adds SLDS resources to the page to allow our Lightning components to be styled with the Salesforce Lightning Design System. If we don’t want SLDS resources added to the page, we need to extend from ltng:outAppUnstyled instead.

This is lightning component with in visualforce page

In the above Visualforce page, apex:includeLightning tag imports necessary dependencies and scripts to enable Visualforce to act as Lightning component container.

We can use $Lightning.use() method in JavaScript to refer to Lightning Application which extends ltng:outApp.

We can use $Lightning.createComponent create Lightning Component dynamically.

We can call $Lightning.use() multiple times on a page, but all calls must reference the same Lightning dependency app.
