I’m not sure how to solve this one, when defining the type annotation for the personObject like so:

let personObject: {name: string, age: number, giftWish: string, success:boolean}

I get errors:

  • ‘personObject’ refers to a value, but is being used as a type here.
  • the personObject param for sayHappyBirthdayWithObject still considers itself the any type.

Any ideas? Thank you.

It is just a bug of editor probably.
Met same problem.

Steps to avoid:
declare let personObject above the function with all needed params;
add personObject : personObject in function;
click Run >> observe an error;
copy “: {name: string, age: number, giftWish: string, success:boolean}” to function.

A bit late but the annotation needs to be on the param in the function.
function(personObject: {name: string, age: number, giftWish: string, success: boolean})

and make sure there is a space between the : and the { , this got me with this error.

Can confirm that it is checking for a space after personObject:

Yes, it was the space.
