Do not use forEach with async-await

TLDR: Use for...of instead of forEach() in asynchronous code.

For legacy browsers, use for(...;...;...) or [].reduce()

To execute the promises in parallel, use Promise.all([].map(...))

IntelliJ and recursive data structures

You may need to override toString on any recursive or deeply-nested data structure, since IntelliJ will ask the Java Debugger (JDB) to call toString all the time. This will blow up your memory.

Remote debugging

Useful for any number of reasons: testing on a different OS, using lots of memory/cpu resources you don't have locally, etc.

See an Intellij / IDEA guide for background.
