## async-method-chaining.js
/*

  Method chaining is useful way to construct readable software. It is a process
  where each method returns an object, allowing the calls to be chained together
  in a single statement without requiring variables to store the intermediate
  results. However, how can we achieve this in the face of JavaScript’s
  asynchronous function? Here is a simple solution for this tricky issue.
