Awesome work getting the hang of the async...await syntax! Let’s review what you’ve learned:

  • async...await is syntactic sugar built on native JavaScript promises and generators.
  • We declare an async function with the keyword async.
  • Inside an async function we use the await operator to pause execution of our function until an asynchronous action completes and the awaited promise is no longer pending .
  • await returns the resolved value of the awaited promise.
  • We can write multiple await statements to produce code that reads like synchronous code.
  • We use try...catch statements within our async functions for error handling.
  • We should still take advantage of concurrency by writing async functions that allow asynchronous actions to happen in concurrently whenever possible.
