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

The isWeekend function from the date-fns package in JavaScript is used to determine whether a given date is a weekend day or not. This function takes a Date object as a parameter and returns a boolean value indicating whether the given date is a Saturday or Sunday.

Here's an example of how to use the isWeekend function in JavaScript:

index.tsx
const dateFns = require('date-fns');

const today = new Date(); // get the current date
const isWeekend = dateFns.isWeekend(today); // check if it is a weekend day

if (isWeekend) {
  console.log('Today is a weekend day!');
} else {
  console.log('Today is not a weekend day!');
}

In this example, we first import the date-fns package and create a new Date object representing today's date. We then call the isWeekend function, passing in the today variable as the parameter. The function returns a boolean value, which we assign to the isWeekend variable.

Finally, we use a conditional statement to check the value of the isWeekend variable and log the appropriate message to the console.
