Do transformations of type "translate" fulfill your needs?

Here is an example:

var curve1 = board.create('curve', [t => Math.cos(t), t => 3 * Math.sin(2 * t)]);

var t = board.create('transform', [0.5, 1], {type: 'translate'});

var curve2 = board.create('curve', [curve1, t], {strokeColor: 'red'});
