In the past we could just use developer code tool to create all of the different components.
However, for us to develop LWC we must do a few things.
Install Visual Studio https://code.visualstudio.com/
Install CLI & run update
3. Salesforce Extension Pack
4. Install Java SDK
5. Change VS code settings
Go to File | Preferences | Settings
Search for "Apex Java"
Change the path to: C:\Program Files\Java\jdk1.8.0_321 (this was my default installation)
