Four Prefixes That Eliminate Boolean Ambiguity

Ambiguous boolean variable names are a hidden source of bugs in every codebase, silently draining development velocity. This guide introduces a universal four-prefix naming system (IS, HAS, CAN, SHOULD) that transforms inconsistent and confusing code into self-documenting clarity. By adopting this single, language-agnostic convention, teams immediately reduce cognitive load, prevent logic errors, and dramatically improve code collaboration.
