Palindrome

An Palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward.

Problem 1

Tell if a word is a palindrome

Solution

You just need to check if the reverse of a string is the same as the string.

function isPalindrome(str:string) {
  return str.split('').reverse().join('') === str;
}

Since reverse is not a function on a JavaScript string you just leverage the one on Array
