ELI5 — The Vibe Check
DX (Developer Experience) is UX but for developers. How painful is it to set up the project? How fast is the feedback loop? Good DX means devs are happy and productive. Bad DX means hours wasted on confusing tooling, slow builds, and terrible error messages.
Real Talk
Developer Experience encompasses all aspects of a developer's interaction with a codebase, framework, or tool — including documentation quality, setup friction, error message clarity, build speed, and tooling ergonomics. High DX correlates with developer productivity and satisfaction.
