Moment Add Days Non Destructive

Adding days to a date is a common requirement in web development. Moment.js is a popular JavaScript library that can be used to add days to dates in a non-destructive manner.

Method 1: Using Moment.js library

Moment.js provides the add() method that can be used to add days to a date in a non-destructive manner. Here is an example:

// Current date
var currentDate = moment();
// Add 7 days to current date
var newDate = currentDate.add(7, 'days');

The above code will add 7 days to the current date without modifying the original date value. The resulting newDate variable will hold the updated date value.

Method 2: Using vanilla JavaScript

If you don't want to use a library like Moment.js, you can use vanilla JavaScript to add days to a date. Here is an example:

// Current date
var currentDate = new Date();
// Add 7 days to current date
var newDate = new Date(currentDate.getTime() + (7 * 24 * 60 * 60 * 1000));

The above code uses the getTime() method to get the Unix timestamp of the current date, adds the number of milliseconds in 7 days, and creates a new Date object with the updated timestamp value. This approach is also non-destructive as it does not modify the original date value.

Conclusion

Adding days to a date in a non-destructive manner is an important requirement in web development. Moment.js provides an easy way to achieve this, but vanilla JavaScript can also be used if you don't want to use a library. Both methods are non-destructive and can be used depending on your preference and project requirements.
