[WIP] Make toBe matcher error message more helpful for objects and arrays #4277

I wonder if that would be some performance hit for large objects |
| return ( | ||
| matcherHint('.toBe') + | ||
| '\n\n' + | ||

equity? Shouldn't it be "equality"?
I think it's still useful to keep some of the information from before, at least "Expected value to be (using ===) but they are different objects/arrays. […]”. What do you think?

What if we just add the new message below and leave the rest as it was? Just a new line as extra information

Yeah, I think that is preferable. Can you keep it on the same line as the "no visual difference" sentence?

This is so bloody fantastic that I searched for the error string "You probably need to use" in the git repo,, found the line, used git blame to find who introduced it, found this PR, all to tell you @rogeliog if we ever meet I shall buy you all the beers! 🍻 I love error messages like this. It's like peer programming with an AI. |
