Is it possible to get intellisense for Javascript in Visual Studio Code even without using typings?

Is it possible to have intellisense support in Visual Studio Code for a 3rd party library installed via npm, even if there is no typings file available?

I have noticed this feature working in IntelliJ/Webstorm, so I believe it might be feasible. However, I couldn't find any information in the Visual Studio Code documentation confirming if this feature is supported.

Important: I am specifically interested in having intellisense while coding in .ts files, not in .html files or any other contexts.
