// Here's a similar example which uses a class:

class AddNumbers {
  private n: number;

  constructor(start = 0) {
    this.n = start;
  }

  public add(inc = 1) {
    this.n = this.n + inc;
    return this;
  }

  public print() {
    console.log(this.n);
    return this;
  }
}

// Here it is in action:

new AddNumbers(2).add(3).add().print().add(1);

// This example used the TypeScript
// type inference to provide a way to
// provide tooling to JavaScript patterns.
