C# I can understand being so low, since it's almost always written in Visual Studio or MonoDevelop (both of which provide autocompletion). But how is JavaScript the next lowest?
Hmm, I guess it's because length is a commonly used function in Javascript, but not in other languages. In Python you do len(list) instead, so the word length is more likely to appear in comments and therefore less likely to be corrected.
Because the built-in .length property is frequently used, and will fail if misspelled.
Whereas C and C++ programs tend to have a lenght operator implemented by the programmer, and from there the error gets snowballed by IDEs and debuggers.
C# is also a compiled language, so you wouldn't be able to get anything to run with a typo like that hanging around. I find it surprising that there are so many commits making that mistake!
Being a compiled language isn't sufficient to prevent "no method" errors. It's completely possible for a compiled language to define methods at runtime or use duck typing.
