function palindrome(str) {
  
// Used to find a non-word character - a word character is a character from a-z , A-Z , 0-9 , including the underscore character that we have putted bellow
  str = str.replace(/[\W_]/g,"").toLowerCase();  
  
  
  
  var som = str.length; // nr caractere
  
  
  for (var j=0; j<(som-1)/2; j++) { 
    
    if (str.charAt(j)!==str.charAt(som-1-j)){  // str.charAt() return the letter at that position
        
      return false;
      
    }
    
  }
  return true;    // the false statement should be first and true statement must be outside the for loop , otherwise it will break the function after the first match and return inaccurate result
}
