  // :)
  var ob = {
    "&":'&',
    "'":''',
    '"':'"',
    "<":'&lt;',
    ">":"&gt;"
  }
  let hna = str.split('')
  if(str.match(/[&'"<>]/)){
    return hna.map(function(x, b){
      if(x.match(/[&<>'"]/)){
        return hna.replace(x,ob[x])
      }
      
    }).join('')
  }
  else{
    return str;
  }
