The 80 20 Guide to Async Await
summary
Covers concrete ES2017 async/await behavior with runnable examples on node 7.6+ and Node 8, showing fetch/node-fetch to hit httpbin.org/ip and an fs-wrapped Promise that prints its own source. Demonstrates that awaiting pauses the async function but does not block the event loop (examples that print “2 1 3” versus “1 2 3”), contrasts sequential for-loops with the broken forEach pattern, explains try/catch vs top-level .catch, shows Express needs a wrapper while Mocha already supports async functions.
