What is Promise.then()?
Name if the international body that defines the JavaScript specification.
What is ECMA?
In Node.js, streams are abstract interface for working with ________.
What is streaming data?
Since JavaScript execution in Node.js is single threaded, this term refers to the event loop's capacity to execute JavaScript callback functions after completing other work.
What is Concurrency?

What is Sync?
This statement allows a program to evaluate an expression and attempt to match the expression's value to a case label. If a match is found, the program executes the associated statement.

What is the Worker Pool?

This blocks the event loop disastrously by potentially taking exponential time, exposing you to REDOS on "evil input".
What is a vulnerable regular expression?
This loop is what allows Node.js to perform non-blocking I/O operations — despite the fact that JavaScript is single-threaded — by offloading operations to the system kernel whenever possible.
What is Event?
