Nothing if you refer to one of the other referenced graph [1]. In this graph it's a derivative of C and C++. IMHO, regarding JS, nobody can affirm from which languages it is a derivative unless Brendan Eich himself.
By the way, such a graph does not give much information about the influences that make a language evolves. It's like saying English is a fork of German and since the split neither of these languages have been influenced by others (e.g. Lambdas have been added to Java only because one of the mainteners had a new idea one morning while taking its shower)
