Encodes a set of form elements as a query string.

  • Use the FormData constructor to convert the HTML form to FormData.
  • Use Array.from() to convert to an array, passing a map function as the second argument.
  • Use and encodeURIComponent() to encode each field's value.
  • Use Array.prototype.join() with appropriate arguments to produce an appropriate query string.
const serializeForm = form =>
  Array.from(new FormData(form), field =>'=')
