如何将ES6转换回ES3 /简单javascript？

Question

如何将以下代码转换为简单的javascript？

const prescriptions = [...document.querySelectorAll("[data-purpose='selected-prescription']")];

const titleDescStr = prescriptions.map(prescription => {
  const [titleElem, descElem] = [...prescription.children];
  return titleElem.textContent + ' ' + descElem.textContent;
}).join('|');

console.log(titleDescStr);

请帮助将以上代码转换为javascript谢谢。

我尝试使用babel进行以下操作，但无法正常工作。

function _nonIterableSpread() { throw new TypeError("Invalid attempt to spread non-iterable instance"); }

function _iterableToArray(iter) { if (Symbol.iterator in Object(iter) || Object.prototype.toString.call(iter) === "[object Arguments]") return Array.from(iter); }

function _arrayWithoutHoles(arr) { if (Array.isArray(arr)) { for (var i = 0, arr2 = new Array(arr.length); i < arr.length; i++) { arr2[i] = arr[i]; }return arr2; }}


 var prescriptions = _toConsumableArray(document.querySelectorAll("[data-purpose='selected-prescription']"));

var titleDescStr = prescriptions.map(function (prescription) {
  var _ref = _toConsumableArray(prescription.children),
      titleElem = _ref[0],
      descElem = _ref[1];

  return titleElem.textContent + ' ' + descElem.textContent;
}).join('|');

  console.log(titleDescStr);```
