This episode covers the five podcast episodes I found most interesting and wanted to share links to during the two week period starting March 16, 2020. These podcast episodes may have been released much earlier, but this was the fortnight when I started sharing links to them to my social network followers.
CHRIS FERDINANDI ON GREATER THAN CODE
The Greater Than Code podcast featured Chris Ferdinandi with hosts Rein Henrichs and Jacob Stoebel. Chris is a proponent of plain vanilla JavaScript. He says that modern web development has grown so much in scope and complexity that it makes it difficult for beginners to get started and it can negatively impact the performance of the web for users in ways that developers with fast machines don’t always feel.
One of the reasons things are the way they are today, Chris says, is because a lot of backend developers migrated to the front end because that was where the exciting stuff was happening and they brought with them their approaches and best practices.
The front end, however, is a very different medium. In the back end, you have control over how fast the server is, when things run, the operating system, etc. On the front end, you have none of this. People are accessing what we build on a variety of devices that may or may not be able to handle the data we’re sending and may have unpredictable internet connections.
If a file fails to download or the user goes through a train tunnel and we’ve built things in a modern JavaScript-heavy way, the whole house of cards falls apart on these users. Chris would like people not to abandon JavaScript altogether, but to be a little more thoughtful about how we use it.
Modern web development involves a few things: frameworks, package managers, and doing more and more things (such as CSS) in JavaScript. All of this JavaScript has the effect of slowing down performance because 100KB of JavaScript is not the same as 100KB of CSS, a JPEG, or HTML because the browser needs to parse and interpret it.
Because of these performance problems, single page apps have become more popular. But now you’re recreating in JavaScript all the things the browser gave you out of the box like routing, shifting focus, and handling forward and back buttons. You’re solving performance problems created by JavaScript with even more JavaScript, which is the most fragile part of the stack because it doesn’t fail gracefully. If a browser encounters an HTML element it doesn’t recognize, it just treats it as a div and moves on. If you have a CSS property you mis-typed, the browser ignores it. But if you mistype a variable in JavaScript, the whole thing falls apart and anything that comes after that never happens. 
For Chris, a better approach to web development is one that is more lean and more narrowly-focused on just the things you need. His first principle is to embrace the platform. For example, a lot of people don’t realize that DOM manipulation that used to be really hard years ago is really easy these days in vanilla JavaScript. Also, many of the things that JavaScript was required for in the past can be done more efficiently today with HTML and CSS.
He also says that we need to remember that the web is for everyone. Because we are often using high-end computers, the latest mobile devices, and fast internet connections, we forget that this is not the experience for a majority of web users. We build things that work fine on our machines but are pain
