FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Here's an example of how to debug Mocha v4 if it hangs.
Ensure you're using a Node.js 8 or newer (or any version with async_hooks support).
If you run your test, you'll notice it hangs:
$ mocha test.js
| const crypto = require('crypto') | |
| const Swarm = require('discovery-swarm') | |
| const defaults = require('dat-swarm-defaults') | |
| const getPort = require('get-port') | |
| const readline = require('readline') | |
| /** | |
| * Here we will save our TCP peer connections | |
| * using the peer id as key: { peer_id: TCP_Connection } | |
| */ |
None of the string methods modify this – they always return fresh strings.
charAt(pos: number): string ES1
Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).
