Answer 1

EDIT: As pointed out by @RobG the dates are in the ISO format so there is no need for dates at all:

if ('2022-04-30' < '2022-05-30')
  console.log('true')

However this does not work with other date formats, for example:

if ('30-04-2022' < '30-05-2020')
  console.log('returns true, but is incorrect')
  
if (new Date('30-04-2022') < new Date('30-05-2020'))
  console.log('returns false')

ORIGINAL ANSWER: You are trying to compare strings not dates. Try this:

const date1 = new Date('2022-04-30');
const date2 = new Date('2022-05-30');

if (date1 < date2) {
  console.log('true');
}

Or shorter:

if (new Date('2022-04-30') < new Date('2022-05-30'))
  console.log('true');
