How to use the @microsoft/sp-lodash-subset.has function in @microsoft/sp-lodash-subset

private _columnClick = (ev: React.MouseEvent, column: IColumn): void => {
    // Find the field in the viewFields list
    const columnIdx = findIndex(this.props.viewFields, field => field.name === column.key);
    // Check if the field has been found
    if (columnIdx !== -1) {
      const field = this.props.viewFields[columnIdx];
      // Check if the field needs to be sorted
      if (has(field, 'sorting')) {
        // Check if the sorting option is true
        if (field.sorting) {
          const sortDescending = typeof column.isSortedDescending === 'undefined' ? false : !column.isSortedDescending;
          const sortedItems = this._sortItems(this.state.items, column.key, sortDescending);
          // Update the columns
          const sortedColumns = this.state.columns.map(c => {
            if (c.key === column.key) {
              c.isSortedDescending = sortDescending;
              c.isSorted = true;
            } else {
              c.isSorted = false;
              c.isSortedDescending = false;
            }
            return c;
          });
          // Update the grouping
