问题
If I intentionally make a typo in my code I will get an error. Here is the correct code:
declare const State: TwineState;
If I delete the last character and then type tsc on the command line, it gives me this error:
tsc/prod.spec.ts:7:22 - error TS2304: Cannot find name 'TwineStat'.
7 declare const State: TwineStat;
But Visual Studio Code doesn't seem to realize there's any error.
How I get my editor to show me the same errors that the tsc command recognizes? I'm pretty new to all these technologies so I don't know what information would be helpful to troubleshoot, but here are my config files:
