Ruby-reverse ', upcase ' & '. Downcase '

Let's say we don't know anything about it when we start looking at this method. Then our field test may deduce its effect.

" Bonnie ". Reverse

What is the result of the operation?

"Einnob"

And then what do we know about this method? Yes, this is a reversal method. At this time is not think and JS very much like, haha, not very much like, is the same, get the result is the same, now is not a better understanding of the other two, let's go,go, go.

" Bonnie ". upcase

Result

" BONNIE "

Yes, this is the way to capitalize the string, and the other is not a good guess. We still have to try.

" Bonnie ". Downcase

Result

" Bonnie "

is not quite easy. So let's try a couple of them together.

" Bonnie ". Reverse.upcase

Result

" Einnob "

Is there any judgment on the outcome?

Let us continue our efforts to make a breakthrough in the practical use of complex usage. By the end of my study, I'll have a project. wow haha ~ ~ ~. Work together.
