TypeScript：如何指定内联对象的类型？

Question

I've got some code that compiles when I do this:

    const createCallback: any = {
        toBuffer: (func: any) => {
            return func();
        }
    };
    pdfCreateMock.returns(createCallback);

How do I get it to compile like this?

    pdfCreateMock.returns({
        toBuffer: (func: any) => {
            return func();
        }
    });

I don't know how to say that the inlined object is of type any . This is the error:

Answer 1

Cast to any

pdfCreateMock.returns(<any>{
        toBuffer: (func: any) => {
            return func();
        }
    });
