Public properties can be created via Instance public fields

// ES2022

class InstPublicClass {
  // Instance public field
  instancePublicField = 0; // (A)

  constructor(value) {
    // We don’t need to mention .property elsewhere!
    this.property = value; // (B)
  }
}

const inst = new InstPublicClass('constrArg');

Public properties can be created via Static public fields

// ES2022

const computedFieldKey = Symbol('computedFieldKey');
class StaticPublicFieldClass {
  static identifierFieldKey = 1;
  static 'quoted field key' = 2;
  static [computedFieldKey] = 3;
}
console.log(StaticPublicFieldClass.identifierFieldKey) //output -> 1
console.log(StaticPublicFieldClass['quoted field key']) //output -> 2
console.log(StaticPublicFieldClass[computedFieldKey]) //output -> 3
