is this a palindrome code example

Example 1: check palindrome

bool isPlaindrome(string s)
	{
	   int i=0;
	   int j=s.length()-1;
	   while(i<j)
	   {
	       if(s[i]==s[j])
	       {i++;
	   j--;}
	   else break;
	   }
	   if (i==j || i>j) return 1;
	   else return 0;
	}

Example 2: palindrome

function isPalindrome(text) {
  return [...text].reverse().join('') === text;
}

isPalindrome = text => {
	return [...text].reverse().join('') === text;
}

isPalindrome = text => [...text].reverse().join('') === text;
