Use method chaining

This pattern is very useful in JavaScript and you see it in many libraries such as jQuery and Lodash. It allows your code to be expressive, and less verbose. For that reason, I say, use method chaining and take a look at how clean your code will be. In your class functions, simply return this at the end of every function, and you can chain further class methods onto it.

Bad:

class Car {
  constructor(make, model, color) {
    this.make = make;
    this.model = model;
    this.color = color;
  }

  setMake(make) {
    this.make = make;
  }

  setModel(model) {
    this.model = model;
  }

  setColor(color) {
    this.color = color;
  }

  save() {
    console.log(this.make, this.model, this.color);
  }
}

const car = new Car("Ford", "F-150", "red");
car.setColor("pink");
car.save();

Good:

class Car {
  constructor(make, model, color) {
    this.make = make;
    this.model = model;
    this.color = color;
  }

  setMake(make) {
    this.make = make;
    // NOTE: Returning this for chaining
    return this;
  }

  setModel(model) {
    this.model = model;
    // NOTE: Returning this for chaining
    return this;
  }

  setColor(color) {
    this.color = color;
    // NOTE: Returning this for chaining
    return this;
  }

  save() {
    console.log(this.make, this.model, this.color);
    // NOTE: Returning this for chaining
    return this;
  }
}

const car = new Car("Ford", "F-150", "red").setColor("pink").save();
