About JS in Prod
For the work between finding a problem and understanding it.
I’m Niko Minadze. JS in Prod is about how JavaScript behaves in the applications people build, deploy, and maintain. It’s for frontend and backend developers working through concrete implementation, debugging, and reliability problems.
You’ll find practical explanations of async execution, promises, event loops, modules, browser APIs, DOM events, and network requests. The blog also covers Node.js services, error handling, memory, performance, testing, dependencies, and deployment. Frameworks come up when JavaScript behavior is central to the answer.
The focus is on modern browsers, Node.js, and relevant alternative JavaScript runtimes. When a solution depends on the runtime, module format, or version, those differences matter here.
