071How does date-fns.differenceInMilliseconds work?
date-fns.differenceInMilliseconds is a function provided by the date-fns library that calculates the difference in milliseconds between two dates or timestamps. When called with two arguments, the function calculates the difference between the first date and the second date in milliseconds. The dates can be either Date objects or timestamp strings in ISO 8601 format. Here's the syntax for date-fns.differenceInMilliseconds: javascript Copy code {{{{{{{ differenceInMilliseconds(dateLeft, dateRight) dateLeft: The date to subtract from. dateRight: The date to subtract. The function returns the difference in milliseconds between the two dates as a number. Here's an example of how to use date-fns.differenceInMilliseconds to calculate the age of a person in milliseconds: javascript Copy code {{{{{{{ class="!whitespace-pre hljs language-javascript">const { differenceInMilliseconds } = require('date-fns'); const birthDate = new Date('2000-01-01'); const now = new Date(); const ageInMilliseconds = differenceInMilliseconds(now, birthDate); console.log(`Age in milliseconds: ${ageInMilliseconds}`); In this example, we create two Date objects representing the person's birth date and the current date. We then use date-fns.differenceInMilliseconds to calculate the difference between the two dates in milliseconds. The result is logged to the console. Note that date-fns.differenceInMilliseconds can be useful in many situations where the difference between two dates or timestamps needs to be calculated with high precision. It's important to note that the function returns the absolute value of the difference, so the order of the arguments does not matter.

1 2 3 4 5 6 7 8 9 10const { differenceInMilliseconds } = require("date-fns"); const date1 = new Date("2022-04-07T01:00:00Z"); const date2 = new Date("2022-04-07T02:30:00Z"); const difference = differenceInMilliseconds(date2, date1); console.log( `The difference in milliseconds between the two dates is ${difference}.` );
In this example, we use date-fns.differenceInMilliseconds to calculate the difference between date2 and date1 in milliseconds. The result is logged to the console.
