Actual Behavior

Clicking a link to wikipedia brings me to a broken page.

Expected Behavior

Should arrive at wikipedia page

Steps to reproduce

Go to https://p5js.org/reference/p5.FFT/logAverages/
Click link in description "Octave Bands"
Arrive at https://en.wikipedia.org/wiki/Octave_band/, but wikipedia doesn't expect the trailing slash.
This same issue happens for all links to wikipedia. I found more by going to https://github.com/processing/p5.js/blob/v1.11.8/lib/addons/p5.sound.js and searching for "wiki"

Would you like to work on the issue?

nope.
