In JavaScript. How can you add all the fields from an object to the fields of the class?

  I have a class that only takes one object in its constructor. For convenience, I would like not to manually write down, enter the object's fields by some algorithm or method. How can this be done? Here's an example:
  

  class A {
      constructor(config) {
          this.a = config.a
          this.b = config.b
          ...
          // чем это можно заменить?
      }
  }
