Checking if Date is a Weekend

To check if a given date is a weekend, follow these steps:

  • Open the Terminal/SSH and type node to start practicing coding.
  • Use Date.prototype.getDay() method to get the day of the week as a number (0-6), with Sunday being 0 and Saturday being 6.
  • Check if the day is a weekend by using a modulo operator (%) and comparing it to 0 or 6.
  • Omit the argument, d, to use the current date as default.

Here's an example code snippet that you can use:

const isWeekend = (d = new Date()) => d.getDay() % 6 === 0;

To test the function, simply call it without any argument:

isWeekend(); // true or false (depending on the current date)

This will return true if the current date is a weekend (Saturday or Sunday) and false otherwise.

Summary

Congratulations! You have completed the Date Is Weekend lab. You can practice more labs in LabEx to improve your skills.
