It sounds like a joke, but it’s not. Really! In addition, C did borrow a few concepts from B, so this seemed like a natural progression in naming. But B wasn’t called B because it came after A. B was an implementation of BCPL. In case you were wondering, JetBrains has no plans to create an IDE for B programming, but B-Line would be the perfect name for such a tool.

This is an interesting discussion, proposed by Derek Comartin. How important is domain knowledge vs. technical knowledge? Why don’t more companies require a certain level of domain knowledge? What do you think? Drop your reply in the comments.
I’m really curious about the software industry’s love for making language/framework/tools the top priority of knowledge and experience. Why isn’t the type/domain of software you develop the most important thing? Ex, hiring C# developer vs. hiring a developer for insurance.— Derek Comartin (@codeopinion) August 6, 2021
