It does still have the other similarities; it has closures and a prototype based object system. In the 90s we only had boring Blub languages, so most of the influence that allowed such powerful concepts came from Lisp. (Though I think the prototypes are from Self.)

JS has other differences on the “correctness” spectrum, like all numbers are doubles instead of bignums. But even if that’s “incorrect”, just imagine how much more memory your Chrome tabs would use if you let people use bignums everywhere.

Bye, why would a fully numeric tower js only use the least machine friendly format everywhere ? Did I miss something ?

do you have any link to a source for this claim?

AFAIK JavaScript started as a language called Mocha, which was hacked together in a few days: Java syntax, Scheme functions + Self object system + plus a bunch of other things.

At that time: no symbols, no s-expressions, no cons cells, no lists, no macros, no tail call optimization, ...
