What Is?
Plain-language explanations of programming tools, frameworks, and technologies used in modern software development.
Clear, practical explanations of the tools and technologies we work with every day — what each one is, what problem it actually solves, and where it fits in a system you have to maintain for years.
A lot of technical writing assumes you already know why a tool exists before it tells you how to use it. These guides start a step earlier. The goal is the kind of understanding that helps you make a decision — when a tool is the right choice, when it isn’t, and what the trade-offs are — not just a list of commands to copy.
That matters because the cost of a technology choice shows up later: in how hard the system is to change, debug, and hand off. We favor the boring, proven option for that reason, and these explainers reflect how we actually weigh the tools we recommend and build with.
