Can you open a separate issue for the class member order rule idea? Similar rule for TS: https://github.com/typescript-eslint/typescript-eslint/blob/master/packages/eslint-plugin/docs/rules/member-ordering.md

Rule name class-body-order is the original idea, I'm open to better suggestions.

Fail

Cases not in order as example in Pass.

Pass

class Unicorn {
   #privateField = 1;

   publicField= 1;

   static staticField = 1;

   constructor() {}

   #privateMethod() {}

   publicMethod() {}

   static staticMethod() {}

   static {
     // static block
   }
}
