This is a link the current source of the Spidermonkey implementation of JS Arrays:

https://searchfox.org/mozilla-central/source/js/src/builtin/Array.cpp

Searching for the word "Perl" shows a list of "Perl-ish methods" like join , reverse, push , etc

 
    /* Perl-ish methods. */
    JS_INLINABLE_FN("join", array_join, 1, 0, ArrayJoin),
    JS_FN("reverse", array_reverse, 0, 0),
    JS_TRAMPOLINE_FN("sort", array_sort, 1, 0, ArraySort),
    JS_INLINABLE_FN("push", array_push, 1, 0, ArrayPush),
    JS_INLINABLE_FN("pop", array_pop, 0, 0, ArrayPop),
    JS_INLINABLE_FN("shift", array_shift, 0, 0, ArrayShift),
    JS_FN("unshift", array_unshift, 1, 0),
    JS_FNINFO("splice", array_splice, &array_splice_info, 2, 0),

. The corresponding Perl functions can be found in perlfunc

I'm sure a repo of JS 1.0 would show more detailed comments regarding Perl
