How to fix Unexpected token?

Question

React

import React from "react";

export default class Chosen extends React.Component {
  componentDidUpdate() {
    // chosen doesn't refresh the options by itself, babysit it
    $(this.refs.select).trigger("chosen:updated");
  }

  handleChange = (a, b, c) => {
    // force the update makes it so that we reset chosen to whatever
    // controlled value the parent dictated
    this.forceUpdate();
    this.props.onChange && this.props.onChange(a, b, c);
  };

  componentDidMount() {
    const props = this.props;
    const select = $(this.refs.select);
    $(select)
      .chosen({
        allow_single_deselect: props.allowSingleDeselect,
        disable_search: props.disableSearch,
        disable_search_threshold: props.disableSearchThreshold,
        enable_split_word_search: props.enableSplitWordSearch,
        inherit_select_classes: props.inheritSelectClasses,
        max_selected_options: props.maxSelectedOptions,
        no_results_text: props.noResultsText,
        placeholder_text_multiple: props.placeholderTextMultiple,
        placeholder_text_single: props.placeholderTextSingle,
        search_contains: props.searchContains,
        single_backstroke_delete: props.singleBackstrokeDelete,
        width: props.width,
        display_disabled_options: props.displayDisabledOptions,
        display_selected_options: props.displaySelectedOptions
      })
      .on("chosen:maxselected", this.props.onMaxSelected)
      .change(this.handleChange);
  }

  componentWillUnmount() {
    $(this.refs.select).off("chosen:maxselected change");
  }

  render() {
    const selectProps = $.extend({}, this.props, { ref: "select" });

    return (
      <div>
        <select {...selectProps}>{this.props.children}</select>
      </div>
    );
  }
}

What am I doing wrong?

Trying to rape a corpse - the component has not been updated for three years. Either find something fresher, or rewrite it yourself (there is work for about five minutes, no more).
