Interesting, I can't actually reproduce this error, it seems to just work. Maybe it was a browser bug that has since been fixed?

I will try to reproduce this error, if it works we can merge this one.

@davepagurek it was dropping these errors for me :

but when I added: let fft = new p5.FFT(); it got resolved, anything else seems fine to me.

Oh does this happen when running tests headless from the other open PR? I'm running npm run test and going to http://localhost:8000/test/?grep=FFT, which is what shows no errors.

Where are you adding the new p5.FFT() line? It also has that in a beforeEach, but maybe something is up with the asynchronous tests 🤔

Ya I am getting that while running the test headless, I added the new line within the function, at the very beginning just like we did for oscillator = new p5.Oscillator();
