Logical Assignment Operators [Feature Request]

[rahbari]

Would you please add logical assignment operators as the proposal is in stage 4:

a ||= b; 
a &&= b;
a ??= b;

Thanks for the report, this does look like a very useful ES2021 feature.

yes, i currently use this syntax for singletons:

class Singleton {
  static instance() {
    return this.instance ?? (this.instance = new this());
  }
}

which can be replaced by:

return this.instance ??= new this();
