JavaScript started as a Scheme inspired language. It has runtime evaluation, a serialized data structure format, first class functions, garbage collection, dynamic typing, functional/imperative/object-oriented features, Many languages are not just looking at the syntax or the user-facing features of the language, but also at the implementation techniques of Lisp-like languages. An early example was Garbage Collection, which was invented for automatic and dynamic memory management of linked lists in the first Lisp implementation. R for example started as an attempt to reimplement S with a Scheme-like runtime.
