JFTR: I do not agree with much that Crockford claims there (maybe I will add 
my remarks on it some day), but the point I wanted to make with this 
reference is where he is correct there: “JavaScript”, if you understand that 
to mean all ECMAScript implementations (and you should not; Crockford 
*oversimplifies* there), is “Lisp in C's Clothing” indeed.

In fact, Brendan Eich, creator of (Netscape) JavaScript, wrote *verbatim* in 
his 2008 blog entry that he “was recruited to Netscape with the promise of 
‘doing Scheme’ in the browser”.  Scheme, too, supports both imperative and 
functional programming as it was influenced by Lisp, and is described as one 
of the main dialects of Lisp (the other being Common Lisp).

<https://brendaneich.com/2008/04/popularity/>
<https://en.wikipedia.org/wiki/Scheme_(programming_language)>

Also, ECMAScript and its implementations ActionScript (Macromedia/Adobe in 
Flash), ECMAScript for XML (formerly, Mozilla in Firefox), JavaScript 
(Netscape et al. in various environments), and JScript (Microsoft in 
Internet Explorer, maybe also Edge)¹ are rightfully listed under

<https://en.wikipedia.org/wiki/List_of_programming_languages_by_type#Functional_languages>

in the “Impure” subsection, along with Lisp and Scheme.  (Whereas AISB, 
Haskell is rightfully listed in the “Pure” subsection.)

    [Not my doing this time, but good to see for a change, as Wikipedia
     unfortunately has a history of propagating misconceptions about
     ECMAScript.]
