For loop in a class definition javascript

Recently I ran into some code that basically looks like :

class A {
  constructor(opts) {
    this.a = {};
  }

  for(x, y) {
   ...

    return {
      async check(id) {
        ... 
      }
   };
  }
...more method definitions in the class
}

I'm wondering how its possible to put a for loop inside a class definition . I can see that it is returning a function, but does this mean that the returned function becomes a member function for the class?

It's not a for loop, it's a method named 'for'.

More or less equivalent to

A.prototype.for = function for( x, y ) {
    ...
    return {
      async check(id) {
        ... 
      }
   };
}
