Yep. It will also surprise people here how few companies and organisations are 'with the times' when it comes to web development or tech stacks. Many don't use containers, package managers or Sass/Less type languages. Even more don't use the likes of React/Vue/Angular, let alone automated testing or webpack type setups. And heck, a depressing number likely don't even use version control. The picture of what's 'normal' in this field (via blogs, Reddit, Hacker News, etc) is as distorted as a picture of what a 'normal' life would be like is on social media sites. If you're at a tech savvy startup or planning to get started as a web developer in Silicon Valley, you'll probably want to know a decent amount of what's on this list. If you're outside of that situation or working contract/freelance/whatever, then you'll only need to know about 50% or so of it.
