Code

const currentYear = new Date().getFullYear();

    years.push(i);
  }

  const handleChange = function handleChange(e) {
    const { year, month } = e.target.form;
    onChange(new Date(year.value, month.value));
  };

  return (
    <form className="DayPicker-Caption">
      <select name="month" onChange={handleChange} value={date.getMonth()}>
