Check if a value is a constructor function

function e(t) {
  if (typeof t != "function" || !t.prototype || t.prototype.constructor !== t)
    return !1;
  if (/^class\s/.test(Function.prototype.toString.call(t)))
    return !0;
  try {
    return Reflect.construct(String, [], t), !0;
  } catch {
    return !1;
  }
}
typeof module < "u" && typeof module.exports < "u" && (module.exports = e, module.exports.default = e);
export {
  e as default
};
