I'm always impressed by how strong the WebStorm intellisense is on pure javascript projects. Somehow it mostly gets jump-to-definition right, even in AngularJS tarpits that are full of ngInject magic.

Try using Typescript? It feels like magic to me anyway :)

Maybe not as great as Intellij, but definitely much better than VSCode

I cannot be as magical due to Javascript's dynamic typing. In Java/Kotlin, the IDE can know all about your classes, types, etc., but with Javascript is has to make some guesses.

I am using Webstorm for my side project and have to use Visual Studio Code for company work. Webstorm is so much better IMO. Everything feels to well integrated, while Visual Studio Code always feels like a toy to me.

I've used it with TypeScript exclusively. My qualms are more about debugging (VS Code creates a temporary Firefox profile in seconds and that's it; in WebStorm you need to configure Firefox to launch a certain way and then setup the debugger), the absence of refactoring options, framework support, etc.
