p5.js version

2.0.0 beta 2

Web browser and version

Chrome 132.0.6834.111

Operating system

MacOSX Sequoia 15.2

Steps to reproduce this

When loading a font with a callback in 2.0, a message is generated to the console that says:
🌸 p5.js says: Expected at most 1 argument, but received more in loadFont(). For more information, see https://p5js.org/reference/p5/loadFont..

Unless the docs are out of date, I thought callbacks were still supported, so we probably shouldn't be logging this message. If I'm wrong about the api changes, then maybe we should log a message about the callback api being no longer supported. I'm not super up to date on all the changes in 2.0 so feel free to close if this is a non-issue!

Steps:
  1. Call loadFont("myfont.ttf", font => {})
  2. Observe the warning in the console
Snippet:

https://editor.p5js.org/aferriss/sketches/dEb0fiahL

function setup() {
  createCanvas(400, 400);
  
  loadFont("Arial.ttf", font => {
    textFont(font);
    // Check console
  })
}

function draw() {
  background(220);
}

Research direction

Start with the loadFont() entry point and reproduce the warning using the linked p5.js Editor sketch in Chrome. Check whether the callback form is still supported in p5.js 2.0.0 beta 2 and identify the expected console behavior; the issue is done when valid callback usage no longer produces a misleading warning, or the message clearly explains that callbacks are unsupported.
