- 44. THE GREMLIN GRAPH TRAVERSAL LANGUAGE WHAT’S THIS GREMLIN NOW? ▸ Gremlin is defined by Apache TinkerPop ▸ Expressive language to define traversals ▸ Yo, what good is a graph db if we can’t traverse it? ▸ Functional language with a fluent syntax ▸ Bindings in Groovy, Java8, Scala, Closure, and more
