How to check whether a sentence is palindrome in TypeScript

Answer 1

function isSentencePalindrome(str: string) {
    // Change the string into lowercase and remove all non-alphanumeric characters
    str = str.toLowerCase().replace(/[^a-zA-Z0-9]/g, "");
    
    return str === str.split("").reverse().join("");
}

console.log(isSentencePalindrome("Top step's pup's pet spot.") ? "yes" : "no");
