Yes, I have noticed that there are many similarities between Perl and JavaScript...the way they handle numbers for example. A variable scalar can hold a string or number, and what you do with it or how you treat it is going to determine whether it's going to be used as a number or a string. Both Perl and JavaScript has the ? : << >> / + - + -- ++ *= /= %= -= += <<= >>= operators. In JavaScript the % modulo operator works a bit differently, but both Perl and JavaScript stores numbers the same way. In JavaScript, you can use arguments[] just like in Perl you can use @_ but in Perl they did away with named arguments. Both JavaScript and Perl have regexes, although JavaScript is a bit limited. When it comes to Unicode characters, Perl requires a module to work with unicode strings, but in JavaScript the support is builtin from the start. In fact, your JavaScript functions and variable names can have unicode characters in them. In JavaScript, you can name your variables to start with a $ sign and write code that resembles Perl. Both Perl and Javascript have the eval function. Perl has "last" and "next," while JavaScript has "break" and "continue." They do the exact same thing. Both Perl and Javascript are quite lenient in the way they parse the source code (unless you use strict and warnings).

Perl has vec(), pack() and unpack() and printf() and sprintf() which are entirely missing from JavaScript. Perl is very efficient at manipulating strings but not so fast working with arrays. JavaScript is just the opposite. It's very fast with arrays but slow with strings. Perl has hashes, while JavaScript has properties. I know, it's not the same, but it's a little bit similar.
