How can I concatenate the strings inside a for loop to solve the Cipher?
I tried to do as it follows, but my result var just show the first letter. What am I doing wrong?
Your code so far
function rot13(str) { // LBH QVQ VG!
var result = "";
for (i = 0; i<str.length; i++){
if (str[i].charCodeAt(0)>=65 && str[i].charCodeAt(0)<78){
result += String.fromCharCode(str[i].charCodeAt(0)+13);
}
else if (str[i].charCodeAt(0)>=78 && str[i]<=90){
result += String.fromCharCode(str[i].charCodeAt(0)-13);
}
else{
result += str[i];
}
return result;
}}
// Change the inputs below to test
rot13("SERR PBQR PNZC");
