Performing async operations with sync.WaitGroup

Sometimes, it is useful to perform a number of operations asynchronously, then wait till they complete before moving on. For example, if an operation requires pulling information from multiple APIs and aggregate that information, it can be helpful to make those client requests asynchronously. This chapter will explore using sync.WaitGroup to orchestrate non-dependent tasks in parallel.
