I have been trying for the past day or so to put something together that could work for this project but what I currently have is not working in any way. I know there are many problems with the code but I am not sure what to change as my skills with javascript are rough. Would anyone have any suggestions?
Here is a snip of what I have so far.
Edit: Here is the code
function strReverse() {
return copyStr.split("").reverse().join("");
}
var copyStr = ("");
function palindrome(str) {
//Step 2: create a copy of the inputed string
copyStr = str.slice();
//Step 3: Change all characters of copy to uppercase and remove
//non-alphanumeric characters
copyStr.toUpperCase();
copyStr.replace(/\W_/gi, '');
//Step 4: Reverse the copy of the string
strReverse();
//Test if the original string matches the copy
if (str == copyStr) {
return "This is a palindrome"
} else if (str !== copyStr) {
return "This it not a palindrome"
}
return palindrome;
}
palindrome("eye");
It is always better if you don’t give us pics of your code but rather just paste it in here so we can copy/paste it ourselves for testing. I would probably not use a global variable for this (I’m referring to copyStr) but I don’t think that is your main problem. Remember, you only want to compare alpha-numeric characters. That applies both to the original string and the reversed string.
Try adding some console.log statements to your code so you can see the code work and debug it.
function strReverse() {
return copyStr.split("").reverse().join("");
}
var copyStr = ("");
function palindrome(str) {
//Step 2: create a copy of the inputed string
copyStr = str.slice();
//Step 3: Change all characters of copy to uppercase and remove
//non-alphanumeric characters
copyStr.toUpperCase();
console.log(“uppercased: “+copyStr);
copyStr.replace(/\W_/gi, '');
console.log(“refined: “+copyStr);
//Step 4: Reverse the copy of the string
strReverse();
console.log(“reversed: “+ copyStr):
console.log(“original: “+ str);
//Test if the original string matches the copy
if (str == copyStr) {
return "This is a palindrome"
} else if (str !== copyStr) {
return "This it not a palindrome"
}
return palindrome;
}
palindrome("eye");
