Measure distance along curves, curvePoint()? in p5.js?

I found a facinating website by Pomax, which appears an exhaustive collection of curve related scenarios and formulae.

The tracing section outlines how equidistant points can be achieved,

Sadly, this is far beyond my quite fundamental experience with programming, and so I will continue to look for p5.js examples and share anything I find here. Thanks again for any pointers posted here
