For some good reference material, search for research articles written by Reed Hainsworth, Ph.D. and Larry Wolf, Ph.D..

Also see Sheri L Williamson's hummingbird articles, starting with the article on Feeding Hummingbirds: The Basics. Also recommended is Sheri's book Attracting and Feeding Hummingbirds.

JavaScript Event Loop

Some notes from these sources:

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/EventLoop
• The Node.js Event Loop, Timers, and process.nextTick()

JavaScript has a runtime model based on an event loop, which is responsible for executing the code, collecting and processing events, and executing queued sub-tasks.

When running Node.js, operations may be offloaded to the system kernel whenever possible, to enable non-blocking I/O opererations despite the single-threaded nature of JavaScript.

Working through GitHub Dependabot alerts

So, Dependabot is alerting me about a "moderate serverity" problem with socket.io. It is recommending that I upgrade socket.io to version 2.4.0 or later.

I do not have socket.io in my package.json dependencies for the project/repo that I'm working in and getting this alert, so I have to try and figure out what dependency I am using that is ending up requiring socket.io.

yarn why

I happen to be using yarn in this project, and have a yarn.lock file. So, I'm going to use yarn why to figure out what is requiring socket.io and using the version with the problem. I could use npm ls if I were using a package.lock file.

React events and binding

While becoming familiar with React/Redux, I ran into an unexpected behavior. I used an onClick event handler for a list item, and when the parent component's render() function was called my event handler function was also called.

I thought, "But, I didn't click anything. Why is my event handler firing?"

Here's what I've found (hopefully I understand this as well as I think I do right now).

Assign XML content to a string in C#

Use a verbatim string literal. It is a string that starts with the @ symbol.
Use a quote escape sequence (""), which produces a single quotation mark.
