How to use the terra-date-picker/lib/DateUtil.getFormatByLocale function in terra-date-picker

constructor(props) {
    super(props);

    this.state = {
      dateTime: DateTimeUtils.createSafeDate(props.value),
      isAmbiguousTime: false,
      isTimeClarificationOpen: false,
      dateFormat: DateUtil.getFormatByLocale(props.intl.locale),
      prevPropsValue: props.value,
    };

    // The dateValue and timeValue variables represent the actual value in the date input and time input respectively.
    // They are used to keep track of the currently entered value to determine whether or not the entry is valid.
    // Unlike dateValue and timeValue, this.state.dateTime is the internal moment object representing both the date and time as one entity
    // It is used for date/time manipulation and used to calculate the missing/ambiguous hour.
    // The dateValue and timeValue are tracked outside of the react state to limit the number of renderings that occur.
    this.dateValue = DateTimeUtils.formatMomentDateTime(this.state.dateTime, this.state.dateFormat);
    this.timeValue = DateTimeUtils.hasTime(this.props.value) ? DateTimeUtils.formatISODateTime(this.props.value, 'HH:mm') : '';
