missing parenthesis in call to x.bandwidth() method

[godinenbicicleta]

In the file:
udemy-d3/05/5.07/js/main.js

Lines 112 and 117, there are missing a () in order to call x.bandwidth()

rects.enter()
    .append("rect")
        .attr("fill", "grey")
        .attr("y", y(0))
        .attr("height", 0)
        .attr("x", function(d){ return x(d.month) })
        .attr("width", x.bandwidth)    //-------------------->missing parenthesis
        // AND UPDATE old elements present in new data.
        .merge(rects)
        .transition(t)
            .attr("x", function(d){ return x(d.month) })
            .attr("width", x.bandwidth)    //------------------>missing parenthesis
            .attr("y", function(d){ return y(d[value]); })
            .attr("height", function(d){ return height - y(d[value]); });
