Review this JavaScript age calculator.

What a strong answer looks like

Separate real bugs from style. Rank issues by severity, point at the root cause rather than the symptom, and suggest a concrete fix, specific and kind.

1function ageInYears(birthIso) {

2 const b = new Date(birthIso);

3 const now = new Date();

4 const ms = now - b;

5 return Math.floor(ms / (365 * 24 * 60 * 60 * 1000));

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
