k-kawakami d9060f5abd Remove trailing spaces (#6547) 
### changes
#### remove trailing spaces

When I was using example I noticed trailing spaces.
So, this PR removes the trailing spaces of json file, README, and others.

`examples/with-jest-typescript/src/modules/cars/Overview.tsx` also has it, but this time it did not change as tslint error occurs at commit.

Raw Blame History

Circular structure in "getInitialProps" result

Why This Error Occurred

getInitialProps is serialized to JSON using JSON.stringify and sent to the client side for hydrating the page.

However, the result returned from getInitialProps can't be serialized when it has a circular structure.

Possible Ways to Fix It

Circular structures are not supported, so the way to fix this error is removing the circular structure from the object that is returned from getInitialProps.
