export function compileCandidates(
rawCandidates: Iterable,
designSystem: DesignSystem,
{ onInvalidCandidate }: { onInvalidCandidate?: (candidate: string) => void } = {},
) {
// ...

for (let rawCandidate of rawCandidates) {
let candidate = designSystem.parseCandidate(rawCandidate)
if (candidate === null) {
if (onInvalidCandidate) {
onInvalidCandidate(rawCandidate);
} else {
throw new Error(Invalid candidate: "${rawCandidate}");
}
continue; // Bail, invalid candidate
}
candidates.set(candidate, rawCandidate);
}

// ...
}

export function compileAstNodes(rawCandidate: string, designSystem: DesignSystem) {
let candidate = designSystem.parseCandidate(rawCandidate);
if (candidate === null) {
throw new Error(Invalid candidate: "${rawCandidate}");
}

// ...
}

1. Specific Error Messages:
   • Problem: Current error handling mainly involves calling the onInvalidCandidate callback function to handle invalid candidates, and printing corresponding error messages to the console.
   • Optimization Suggestion: Directly throw an error with specific error messages when encountering invalid candidates, providing better insight into what went wrong.
