VSCode and intellisense

Hi Team!

I am just starting out and use vsCode as my editor. I am a seasoned C# programmer however first time using three.js.

I would like to know how I can get intellisense working correctly for my project. I am not using node.js or anything fancy - just a simple site with an index.html loading in the js scripts via the tags.

I’d love to poke around in the objects more via intellisense so I can experiement!

Thankyou!
Nathan.
