How Job in coroutine works

Defining the coroutine job

• A coroutine returns a Job
• Using the Job we can create control the coroutine like stopping it, So a Job on a coroutine is a handle to the coroutine.
• More flexibility can be achieved using jobs, we can combine the instances of jobs using join().
• Say Job-A invokes join on Job-B the former won't be executed until later has finished on execution.
• We can also set up a parent and child relation using which we can ensure parent wont complete until child has completed its execution.
