When checking the operation of Prettier, the fits function calculates the width of an empty string as 1 instead of 0. The empty string refers to line 15 in the code, and we are using it as a space.
So i changed space to hardspace

Test Plan

add test case

Why Prettier breaks implements ... even if the line doesn't exceed the width limit.

Prettier's playground has a ruler, making it easier to check the line width.

Thank you for asking.

I also thought it strange at first, so I checked how Prettier was working.
But, I'm not very familiar with the Prettier library, and I don't know whether this is what they intended or if it's a bug.

Prettier would sometimes break a line even when it hadn't exceeded the line length.
It seems like the example I worked on before was one of those cases. previous pr

Do you think this issue is a Prettier error rather than something we need to change?

I personally tend to think this is a bug in Prettier.

Thank you for sharing your thoughts! @ah-yu

@dyc3
Could you also share your thoughts?

[dyc3]

I also feel like this is a bug in prettier, but I also think we should generally try to match prettier. The fix here doesn't seem that complicated.

[Conaclos]

We could open an issue on the Prettier repository.

I've opened prettier/prettier#16723

Closing, it's a prettier bug and they are fixing it
