Nature of issue?

p5 Web Editor doesn't support Private Class Fields

• Enhancement

(Private Class Fields is probably a new thing)

Note that Private Class fields is "an experimental proposal to allow defining private class fields using a hash prefix", hence this is not considered a bug.

Details:

Private class properties, or "Hash" names, as stated in the MDN Docs; are not supported by the Web Editor.

Though the code works, the editor comes with an error.

• Steps to reproduce:

class ClassWithPrivateField {
  #privateField
  constructor() {
    this.#privateField = 42;
    this.something = 23;
  }
}
