Question

I was browsing through the net to find a javascript function which can check whether the date entered by the user is current date or the future date but i didn\'t found a s

Answer 1

ES6 version with tolerable future option.

I made this little function that allows for some wiggle room (incase data coming in is from a slightly fast clock for example).

It takes a Date object and toleranceMillis which is the number of seconds into the future that is acceptable (defaults to 0).

const isDistantFuture = (date, toleranceMillis = 0) => {
    // number of milliseconds tolerance (i.e. 60000 == one minute)
    return date.getTime() > Date.now() + toleranceMillis
}
