See what’s happening? We print a different sentence out to the console
based on the number the user typed in.
For example, that last 
if
check that looks for if the value is <10? That only
happens if the value is not negative, is not zero, is not less than 3, but is less
than 10. Read through it top to bottom a few times to logically follow the
logic.
That code looks good right? Pretty? Easy to read?
No, it looks like absolute shit. It’s an eyesore. Hard to read, hard to
understand, and unpleasant to look at. Here’s the good news; you can make
this 1000x easier if you simply say, “
else if
”. HUH??
How is this possible? Here’s why (if you don’t care, it doesn’t really
matter); the curly braces between those chained “
elses
” and “
ifs
” aren’t
doing anything, nor are putting them on different lines.
It functions exactly the same as doing this:
