It's easier to just describe what it accepts specifically here.

The `options` are the same as for `.stringify()`.

Needs a test to show what happens if the URL already has a query string and a query string is specified.

Also add some tests that does parseUrl and then pass the result to stringifyUrl to make sure they are compatible.

This would be surprising behavior for me. Adding another query item here with the same name actually changes the semantics as now the result would be an array instead of a string.

@sindresorhus you think the result would be https://foo.bar?foo[]=bas&foo[]=bar? I'm not sure what the answer would be.

No, that would be completely wrong as it's a different arrayFormat format.

I'm saying that it should replace instead: 'https://foo.bar?foo=bar'. The behavior should be clearly documented.

#217 (comment) is not done. And the English-prose needs more work (typos + could be better written).

@sindresorhus I’m terribly sorry for absent communication. I'm practicing to write English correctly if you have any suggestion about the typo you can guide
