"...Originally, the Java virtual machine — aka the JVM — only ran code built with the Java programming language, but today, it runs all sorts of other languages..."

I'm confused what your main problem here is, besides it's almost lifted straight from Wikipedia. From Wikipedia: "Although the JVM was primarily aimed at running compiled Java programs, many other languages can now run on top of it." So, as far as I can tell from what's quoted, there's not much wrong with what was said. Please clarify.

Also, isn't Clojure a programming language? Does Wikipedia also lie here? If it's not, then what is it?
