Can't Create Random Point in PaperJs per Documentation

Question

I am using the latest version of PaperJs but when I run the following code from their sample the output is "NaN."

window.onload = function () {
    paper.setup('myCanvas');
    with (paper) {
        // Create a point whose x is between 0 and 50,
        // and y is between 0 and 100
        var point = new Point(50, 100) * Point.random();

        console.log(point);
    }
}

The code works online in sketch.paperjs.org but doesn't work when I try locally via the code above or the following (also outputs "NaN"):

// Make the paper scope global, by injecting it into window:
paper.install(window);
window.onload = function () {
    // Setup directly from canvas id:
    paper.setup('myCanvas');

    // Create a point whose x is between 0 and 50,
    // and y is between 0 and 100
    var point = new Point(50, 100) * Point.random();

    console.log(point);
}

The following works, and all my other PaperJs code works; it's just that I can't seem to create a random point per the documentation.

console.log(new Point(50, 100), Point.random());

Outputs:

Point {x: 50, y: 100} Point {x: 0.8624748098043336, y: 0.8705165661914955}

Answer 1

Are you sure you use the paper.js language and not javascript?

Because the multiply operator can't be overloaded in javascript, you have to use pointA.multiply(pointB);.
