Как исправить эту ошибку цикла в моем коде (Ошибка оценки цикла)

использовать для 

for($i = 0; i<count($request->productname); $i++)
{
    Product::create([
        'productname' => $request->productname[$i],
        'qty' => $request->qty[$i],
    ]);
}

Это более чистый способ, и он будет легче поддерживать методы кодирования и декодирования. Мы храним символы в массиве, где позиция это код. Позволяет использовать для отображения в обоих направлениях. 

// Simple array of chars where their index is the 'code'
let lexicon = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", "~", "`", "!", "@", "#", "$", "%", "^", "&", "*", "(", ")", ">", "<", "-", "_", "+", "=", "{", "", "[", "]", "|", ",", ".", "?", "/", "'", '"', "", ";", " "];

// Function to take a string and encode it using a simple map.
const encodeData = (data, lex) => data.split('').map(c => lex.indexOf(c) + 1);
// Decode does the reverse
const decodeData = (data, lex) => data.map(d => lex[d]);

var encryption = [];
var cvalue = 0;
var code = prompt("Type In Encryption Password [Beta Encryptor]");

alert(encodeData(code, lexicon));

function runner() {
  var abc = document.getElementById('input').value;
  encryption = encodeData(abc,lexicon);
  if (encryption.length % 2 === 1) {
    encryption.push(93);
    alert("The Key was Edited Because The Key needs to be even");
  }   
  document.getElementById('runEncryption').innerHTML = encryption.join();
  alert(encryption); //If this was in the loop, it won't work   
}
<html>
<input type="text" id="input">
<button onclick="runner();">Add Text to Encrypt</button>
<br>
<div id="runEncryption"></div>

</html>

Здесь используется оператор переключения (лучше подходит для этого типа теста.)

[ 116] 

var encryption = [];
var cvalue = 0;

var code = prompt("Type In Encryption Password [Beta Encryptor]");
var codeLength = code.length * 100;
