While completing this challenge, I got stuck as I was unable to find any documentation as how to replace the “_”. I searched multiple places on the web and could not find good documentation. I have also attached my code which is a bit lengthy but still got the job done.
Why does this code work: var strReplace = str.replace(/[\W_]/g,’’);
And why does this code not work: var strReplace = str.replace(/\W+/g,’’);
Code Below:
function palindrome(str){
//var re = /\W+/g;
var strReplace = str.replace(/[\W_]/g,'');
//var stre = str;
var arraySplit = [];
var arrayReverse = [];
var joinReverse = '';
arraySplit = strReplace.split("");
arrayReverse = arraySplit.reverse();
joinReverse = arrayReverse.join("");
if(strReplace.toLowerCase() === joinReverse.toLowerCase()){
console.log(joinReverse.toLowerCase());
console.log(strReplace.toLowerCase());
return true;
}
else{
console.log(strReplace);
console.log(joinReverse);
return false;
}
}
palindrome(“Race_Car”);
