Type inference issues #9

VS Code infers the type correctly as number, not unknown or 1 as the error suggests:

The code itself compiles correctly when running it through the TS compiler directly. So at first, I thought that this may be an tslab issue. However, when executing the same script it in Jupyter, it runs without issues:
