// Write a function that takes a string and returns true if it is a
// palindrome. A palindrome is a string that is the same whether written
// backward or forward. Assume that there are no spaces; only lowercase
// letters will be given.
//
// Difficulty: easy.

function is_palindrome(string) {
  var contraire=string.split("").reverse().join("");
  if(contraire==string)
  {
    return true
  }
  else
  {
    return false
  }
}


// These are tests to check that your code is working. After writing
// your solution, they should all print true.
