I recently saw an Ad for a front end job requiring: "strong Java Scripts" skills.
My instant reaction was, "You keep using that word, I do not think it means, what you think it means."
"Well, you told me I have a plethora. And I just would like to know if you know what a plethora is. I would not like to think that a person would tell someone he has a plethora, and then find out that that person has no idea what it means to have a plethora".
