Description
TypeScript Version: 2.3.4
Code
interface Payload {
a: string,
b: number
}
let doFoo: (payload: Payload) => void;
let executeAction: <P>(
action: (payload: P) => void, payload: P
) => void;
executeAction(doFoo, { a: 'hello', b: 2 }); //no errors, ok
executeAction(doFoo, {}); //no errors, wrong!
executeAction(doFoo, { qwe: 2 }); //errors, ok
executeAction(doFoo, { a: 'hola' }); //no errors, wrong!
doFoo({ a: 'hello', b: 2 }); //no errors, ok
doFoo({}); //errors, ok
doFoo({ qwe: 2 }); //errors, ok
doFoo({ a: 'hola' }); //errors, okExpected behavior:
The lines commented with "wrong!" should show errors.
Actual behavior:
Those lines don't show errors
I added the direct calls to doFoo at the bottom for clarification of what I'm expecting. If I'm doing something wrong please let me know.
