I’m confused why we have to put the colon before the symbol name when selecting by key. Even when we’re using the current standard to where the colon is after the name.
I was a little confused by the instructions for this lesson…it said to "Create a new variable, good_movies", but then after I put my code into the editor, it came back with an error that said “It looks like good_movies isn’t a hash.” I know how to make a hash just fine, but were the instructions supposed to say to make a variable, or was that a typo? I thought that a variable could only have one value, whereas a hash could have any number of key and value pairs. I was under the impression that hashes are thusly distinct from variables, but is that incorrect? Are hashes actually a subset of variables?
Thanks in advance
I found many small details that are misleading throughout all the exercises, I wonder if it is because it’s free content but it’s definitely not precise
