Tests:

Number converter
function dateResolver( value ) { return Number(value ?? 0) || new Date(value).getTime(); } let date; dateArray.forEach((value) => { date = dateResolver(value); }); numberArray.forEach((value) => { date = dateResolver(value); }); stringArray.forEach((value) => { date = dateResolver(value); }); undefinedArray.forEach((value) => { date = dateResolver(value); }); mixedArray.forEach((value) => { date = dateResolver(value); });
Cascading ternary
function dateResolver( value ) { return value === undefined ? 0 : Number.isInteger(value) ? value : value instanceof Date ? value.getTime() : new Date(value).getTime(); } let date; dateArray.forEach((value) => { date = dateResolver(value); }); numberArray.forEach((value) => { date = dateResolver(value); }); stringArray.forEach((value) => { date = dateResolver(value); }); undefinedArray.forEach((value) => { date = dateResolver(value); }); mixedArray.forEach((value) => { date = dateResolver(value); });
