I understand that JavaScript allows for basic parison between dates e.g.,

const dateOne = new Date();
const dateTwo = new Date();

return dateTwo > dateOne;

I can see there is a .toBeGreaterThan() expectation in Jest, but this is only for numbers or big ints. Is there something available for dates to pare one is later than another?

• javascript
• jestjs

• calling .getTime() on a Date object returns the number of milliseconds. – user5734311 Commented Feb 8, 2022 at 17:34
• 3 You might do (+dateOne).toBeGreaterThan(+dateTwo) as + coerces Date to milliseconds. – Kosh Commented Feb 8, 2022 at 17:36

Just use date.getTime(), that'll return the date in unix milliseconds.
