You’re welcome.

You are missing the point:

| $ perl -We 'use strict; print(join(",", split("o+", "foobar")), "\n");'
| f,bar
| 
| $ perl -We 'use strict; print(join(",", split(/o+/, "foobar")), "\n");'
| f,bar
| 
| $ perl -v | head -n 2
| 
| This is perl 5, version 20, subversion 2 (v5.20.2) built for x86_64-linux-
| gnu-thread-multi

vs.

| $ js -e '"use strict"; console.log("foobar".split("o+").join(","));'
| foobar
| 
| $ js -e '"use strict"; console.log("foobar".split(/o+/).join(","));'
| f,bar
| 
| $ js --help | head -n 1
| Usage: node [options] [ -e script | script.js ] [arguments] 
| 
| $ js -v
| v0.10.38

Details can be found there and resources referred there.

Good for you.

As you can see in my postings, nicknames are used differently in Usenet 
(nowadays).

Also, you should choose the Subject header field value more wisely next time 
(as I should have earlier).  See the FAQ on posting for details.
