Hex string output different in browser and server javascript

I want to wrap a series of chars by hex strings, with this little script:

var resultBuffer = [];
var sourceBuffer = "004CS01".split('');

resultBuffer.push("\\x" + "02");

for (var i = 0; i < sourceBuffer.length; i++) {
    resultBuffer.push(sourceBuffer[i]);
}

resultBuffer.push("\\x" + "03");
resultBuffer.push("\\x" + "62");
console.log(resultBuffer);

I am facing a problem where one and the same script creates different output. This is from browser: Fiddle http://jsfiddle.net/m5sUD/ 

["\x02", "0", "0", "4", "C", "S", "0", "1", "\x03", "\x62"]

And this from nodejs server (see http://runnable.com/me/U1NzLLgIj8pXRQq4 ):

[ '\\x02', '0', '0', '4', 'C', 'S', '0', '1', '\\x03', '\\x62' ]

Why is it different? I need the output on the server to be just like in the browser.

resultBuffer values of browser and node.js are same. If you print each value in resultBuffer, node.js and browser print same value.

try below code

for (idx in resultBuffer) console.log(resultBuffer[idx]);

in my pc, node.js and browser print same below values.

\x02
0
0
4
C
S
0
1
\x03
\x62

it's a just matter of representation method of array values in node.js and browser. values are same.

I think it is due to fact that \ is not a special character in browser javascript, while it is a special character in node.js and hence it is escaped by another backslash \
