how to use the areintervalsoverlapping function from date-fns in javascript

You can use the areIntervalsOverlapping function from the date-fns library to check if two intervals overlap. Here's an example:


const { areIntervalsOverlapping } = require('date-fns');

const interval1 = {
  start: new Date(2021, 0, 1, 10), // January 1st, 2021 10:00:00
  end: new Date(2021, 0, 1, 12), // January 1st, 2021 12:00:00
};
const interval2 = {
  start: new Date(2021, 0, 1, 11), // January 1st, 2021 11:00:00
  end: new Date(2021, 0, 1, 13), // January 1st, 2021 13:00:00
};

const overlapping = areIntervalsOverlapping(interval1, interval2);
console.log(`Do the intervals overlap? ${overlapping}`); // true

In this example, we use require to import the areIntervalsOverlapping function from the date-fns library. We then define two intervals with start and end properties, and use the function to check if they overlap.

The function returns a boolean value true if the intervals overlap, and false otherwise.
