/* 
  Async: -"When an async function is called, it returns a Promise. When the async function returns a value,
          the Promise will be resolved with the returned value.When the async function throws an exception or some value,
          the Promise will be rejected with the thrown value.An async function can contain an await expression,
          that pauses the execution of the async function and waits for the passed Promise's resolution,
          and then resumes the async function's execution and returns the resolved value." 
  Await:- "The await expression causes async function execution to pause until  a Promise is fulfilled or rejected, 
          and to resume execution of the async function after fulfillment. When resumed, the value of the await expression is 
          that of the fulfilled Promise.If the Promise is rejected, the await expression throws the rejected value.
