When creating an LWC in Visual Studio Code, it creates a folder for your component with the following files in it:

├── force-app
│    └── main
│        └── default
│            ├── lwc
│            │   ├── driverStats
│            │   │   ├── driverStats.html
│            │   │   ├── driverStats.js
│            │   │   └── driverStats.js-meta.xml

In comparison to Aura-based components, LWC-based components are much simpler. The preceding .js file contains client-side JavaScript logic, including bindings to references made in the .html file. It uses the JavaScript import statement to import other components, libraries, or resources. Because LWC is more standards-based, you can create ES6 modules to share common logic between your components. In addition, you can also use OOP with your components, such as base classes.
