dead-export

an export nothing else references

Deterministic checkblocking by defaultbasecode

The argument

Unused Code

Delete unused exports, interfaces, types, and functions immediately — version control has history. If unsure whether something is used, search before deciding.

The proof

fail

// Nothing in this repo mentions `buildGreeting` — no module, no entry, no
// test. Version control has its history; the file does not need to keep it.
export const buildGreeting = ({ name }: { name: string }): string => `Hello, ${name}.`;
